Magnetization Oscillations and Waves
by A.G. Gurevich G.A. MelkovWritten by two well-known researchers in the field, this useful reference takes an applied approach to high frequency processes including oscillations and waves in ferromagnets, antiferromagnets, and ferrimagnets. Problems evaluated include ferromagnetic and antiferromagnetic resonances, spin waves, nonlinear processes, and high frequency manifestations of interactions between the magnetic system and other systems of magnetically ordered substances as elastic waves and charge carriers.Unlike previous monographs on this subject, which are highly theoretical and written for very advanced readers, this book requires only an average college background in mathematics and experimental physics. It will be a valuable addition to the library of engineers and scientists in research and development for communications applications, and scientists interested in nonlinear magnetic phenomena. It also serves as an excellent introduction to the topic for newcomers in the field.Magnetization Oscillations and Waves not only presents results but also shows readers how to obtain them; most formulas are derived with so many details that readers can reproduce them. The book includes many summaries and tables and detailed references to significant work in the area by European researchers.
Magneto Luminous Chemical Vapor Deposition (Green Chemistry and Chemical Engineering)
by Hirotsugu YasudaThe magneto luminous chemical vapor deposition (MLCVD) method is the perfect example of the "front-end green process." It employs an entirely new process that expends the minimum amount of materials in gas phase, yields virtually no effluent, and therefore requires no environmental remediation. Unlike the "back-end green process," which calls for a
Magnetocaloric Energy Conversion
by Andrej Kitanovski Jaka Tušek Urban Tomc Uroš Plaznik Marko Ožbolt Alojz PoredošThis book provides the latest research on a new alternative form of technology, the magnetocaloric energy conversion. This area of research concerns magnetic refrigeration and cooling, magnetic heat pumping and magnetic power generation. The book's systematic approach offers the theoretical basis of magnetocaloric energy conversion and its various sub domains and this is supported with the practical examples. Besides these fundamentals, the book also introduces potential solutions to engineering problems in magnetocalorics and to alternative technologies of solid state energy conversion. The aim of the book is therefore to provide engineers with the most up-to-date information and also to facilitate the understanding, design and construction of future magnetocaloric energy conversion devices. The magnetocaloric energy conversion represents an alternative to compressor based refrigerators and heat pumps. It is a serious alternative to power generation with low enthalpy heat sources. This green technology offers an opportunity to use environmentally friendly solid refrigerants and the potentially high energy efficiency follows the trends of future energy conversion devices. This book is intended for postgraduate students and researchers of refrigeration, heat pumping, power generation alternatives, heat regenerators and advanced heat transfer mechanisms.
Magnetoelastic Acoustic Emission: Theory and Applications in Ferromagnetic Materials (Springer-AAS Acoustics Series)
by Valentyn Skalskyi Zinoviy NazarchukThe book presents theoretical and experimental studies to establish the relationship between volume jumps of the 90° domain wall in a ferromagnetic material and the magnitude of the half-space surface displacement caused by it. A method of evaluating the influence of the external magnetic field on the stress intensity factor at the tip of the crack-like defects in ferromagnets is discussed. The influence of hydrogen on the generation of magneto-elastic acoustic emission signals of ferromagnets is described. The features of magneto-elastic acoustic emission due to the presence of plastic deformation, structural changes, and volumetric damage in such structural materials are shown.
Magnetoelastic Vibrations and Stability of Magnetically Active Plates and Shells
by Gevorg Y. Baghdasaryan Marine A. MikilyanThis book introduces the reader to methods of mathematical modeling and solving non-stationary (dynamic) problems of the theory of magnetoelasticity, as well as to give an idea of the wealth of physical effects caused by the interaction of electromagnetic and mechanical phenomena in magnetically active elastic thin bodies. The studies are mainly limited to a model of isotropic body under the assumption of small deformations. In the first chapter of the book, based on the basic connected nonlinear equations and relations of mechanics and quasi-static electrodynamics of continuum media, a system of equations of magnetoelasticity, surface conditions, and governing equations describing the behavior of disturbances in a magnetoactive medium interacting with an external magnetic field is obtained. On this basis, in Chapters 2 and 3, using the main equations and relations of magnetoelastic vibrations and stability of magnetically soft, thin plates and shells are obtained. By solving specific applied problems, a number of qualitative and quantitative results were identified, caused by the interaction of mechanical and magnetic phenomena in ferromagnetic thin bodies. An approximate formula is obtained to determine magnetohydrodynamic pressure on the oscillating surfaces of plate flowing by supersonic flow of perfectly conducting gas in the presence of magnetic field. This formula is the generalization of well-known formula obtained on the basis of the classical piston theory of gas dynamics in the case of magneto-gas-dynamic flow. On this basis, it became possible to solve complex problems of aeromagnetoelasticity. In the 4th and 5th chapters magnetoelastic processes in superconducting thin shells located in stationary and non-stationary magnetic fields are studied. Two-dimensional equations and corresponding conditions are obtained, which characterize vibrations and stability of superconducting cylindrical and spherical shells under the influence of the given magnetic field. By solving specific problems, the possibility of loss of both static and dynamic stability of thin superconducting bodies under the influence of external magnetic field has been established. The sixth chapter is devoted to mathematical modeling and investigation of issues of dynamics of magnetostrictive plates in magnetic fields (stationary and non-stationary) of several orientations. To study the processes of magnetoelastic interaction in the plate under consideration with complex physical properties of its material, the main postulates of the classical theories and methods were used. The influence of plate in-homogeneity on the processes under consideration was also studied. Dynamic processes in layered plates have been studied. It is shown that heterogeneity is sufficient to control optimally the studied dynamic processes, especially those that arise as a result of interaction. The last 7th chapter is devoted to the investigation of stability of dielectric thin plates in a supersonic flow of perfectly conducting gas in the presence of magnetic field. The problems were studied in both linear and nonlinear formulations. Based on the formula obtained by the authors specific problems of stability were solved. Influence of magnetic field on the flutter characteristics is studied.
Magnetoelectric Response in Low-Dimensional Frustrated Spin Systems
by Shinichiro SekiElectric control of magnetic properties, or inversely, magnetic control of dielectric properties in solids, is called a magnetoelectric effect and has long been investigated from the point of view of both fundamental physics and potential application. Magnetic and dielectric properties usually show minimal coupling, but it recently has been discovered that magnetically induced ferroelectricity in some spiral magnets enables remarkably large and versatile magnetoelectric responses. To stabilize such helimagnetism, magnetic frustration (competition between different magnetic interactions) is considered the key. In the present work, two of the most typical frustrated spin systems--triangular lattice antiferromagnets and edge-shared chain magnets--have systematically been investigated. Despite the crystallographic simplicity of target systems, rich magnetoelectric responses are ubiquitously observed. The current results published here offer a useful guideline in the search for new materials with unique magnetoelectric functions, and also provide an important basis for a deeper understanding of magnetoelectric phenomena in more complex systems.

by Rachid MasrourThis book undertakes an extensive exploration of manganese-based compounds, such as T₁₋ₓSrxMnO₃ (T = La, Pr; x = 0.35, 0.25) using density functional theory and Monte Carlo simulations with a focus on understanding their electronic, magnetic, and magnetocaloric properties. Ba₁₋ₓSrxFeO₃ (x = 0, 0.2) is also studied via different approximations, offering a comparative perspective. In addition, the book looks at the influence of magnetism using Monte Carlo simulations, revealing crucial parameters and examining the GdCrO₃ system through DFT and Monte Carlo simulation, shedding light on recent experimental observations. Additionally, Monte Carlo studies investigate magnetic and magnetocaloric features of Sr₂FeMoO₆, La₂SrMn₂O₇ bilayer manganite, perovskite ferromagnetic thin films' surface effects, and SmFe₁₋ₓMnxO₃ perovskite. In essence, this book significantly advances our comprehension of magnetic and magnetocaloric phenomena across diverse materials and is well-suited for both experimentalists and computational researchers working in this field.
Magnetoelectronics of Microwaves and Extremely High Frequencies in Ferrite Films
by Alexander A. IgnatievThis book is devoted to an entirely new direction of the magnetoelectronics of millimetric waves in layered structures containing epitaxial ferrite films. The new electrodynamic approach for research of electromagnetic waves in layered bigyrotropic structures- excitation of waves in converters with parallel and orthogonal orientations- is evaluated. In addition, the results of experimental research are mentioned and new methods of not destroying diagnostics of ferrite films magnetic parameters are considered. The discrepancy of resonant frequencies and the magnetic fields corresponding to them, determined from magnetoscopia and electrodynamic theories, is shown. Results of research on parameters of passive devices on milliwatt and kilowatt levels of capacity on millimetric are also explained in this text.

Magnetostatic Modelling of Thin Layers Using the Method of Moments And Its Implementation in Octave/Matlab (Lecture Notes In Electrical Engineering #491)
by Roman SzewczykThis book presents an efficient and robust method of modelling the magnetostatic properties of different technical elements, especially thin layers for magnetic sensors. The solutions presented utilise the principles of the method of moments. However, the principles have been developed both from the point of view of physical analyses as well as from the point of view of numerical optimisation. To enable cost-efficient use of the solutions for commercial applications in industry, the proposed method was implemented as a code optimised for use in the open-source OCTAVE environment. The scripts can be also used with MATLAB software, which is more user friendly, especially for less experienced users.

Magnificent Failure
by Craig RyanLocked in a desperate Cold War race against the Soviets to find out if humans could survive in space and live through a free fall from space vehicles, the Pentagon gave civilian adventurer Nick Piantanida's Project Strato-Jump little notice until May Day, 1966. Operating in the shadows of well-funded, high-visibility Air Force and Navy projects, the former truck driver and pet store owner set a new world record for manned balloon altitude. Rising more than 23 miles over the South Dakota prairie, Piantanida nearly perished trying to set the world record for the highest free fall parachute jump from that height. On his next attempt, he would not be so lucky. Part harrowing adventure story, part space history, part psychological portrait of an extraordinary risk-taker, this story fascinates and intrigues the armchair adventurer in all of us.

The Magnificent Mesquite (Corrie Herring Hooks Series)
by Ken E. RogersA reliable source of food and shelter even in the severest droughts, the mesquite tree sustained American Indians in the Southwest for centuries. Today, mesquite is popular for barbecuing, woodworking, furniture making, flooring, sculpture, jewelry, and food products ranging from honey to jelly and syrup. Even ranchers, who once fought to eradicate mesquite, have come to value its multiple uses on well-managed rangeland. In this book written especially for a general readership, one of the world' leading authorities on mesquite presents a wealth of information about its natural history and commercial, agricultural, and woodworking uses. Ken Rogers describes the life cycle, species, and wide distribution of the mesquite, which is native or naturalized not only in the Southwest and Mexico, but also in India, Africa, Australia, South America, and Hawaii. He discusses the many consumer and woodworker uses of mesquite at length-even giving instructions for laying a mesquite wood floor and making mesquite bean jelly. He also looks into the ways that people are using mesquite in nature, from rangeland management in the Southwest to desertification prevention in arid countries.
Magnificent Rebels: The First Romantics and the Invention of the Self
by Andrea Wulf'Elegantly written, deeply researched and totally gripping' SIMON SEBAG MONTEFIOREIn the 1790s an extraordinary group of friends changed the world. Disappointed by the French Revolution's rapid collapse into tyranny, what they wanted was nothing less than a revolution of the mind. The rulers of Europe had ordered their peoples how to think and act for too long. Based in the small German town of Jena, through poetry, drama, philosophy and science, they transformed the way we think about ourselves and the world around us. They were the first Romantics.Their way of understanding the world still frames our lives and being.We're still empowered by their daring leap into the self. We still think with their minds, see with their imagination and feel with their emotions. We also still walk the same tightrope between meaningful self-fulfilment and destructive narcissism, between the rights of the individual and our role as a member of our community and our responsibilities towards future generations who will inhabit this planet. This extraordinary group of friends changed our world. It is impossible to imagine our lives, thoughts and understanding without the foundation of their ground-breaking ideas.
