WAVE TURBULENCE is a state of a system of many simultaneously excited and interacting waves characterized by an energy distribution which is not in any sense close to thermodynamic equilibrium. Such situations in a choppy sea, in a hot plasma, in dielectrics under arise, for example, a powerful laser beam, in magnets placed in a strong microwave field, etc. Among the great variety of physical situations in which wave turbulence arises, it is possible to select two large limiting groups which allow a detailed analysis. The first is fully developed wave turbulence arising when energy pumping and dissipation have essentially different space scales. In this case there is a wide power spectrum of turbulence. This type of turbulence is described in detail e. g. in Zakharov et al. 1 In the second limiting case the scales in which energy pumping and dissipation occur are the same. As a rule, in this case a narrow, almost singular spectrum of turbulence appears which is concentrated near surfaces, curves or even points in k-space. One of the most important, widely investigated and instructive examples of this kind of turbulence is parametric wave turbulence appearing as a result of the evolution of a parametric instability of waves in media under strong external periodic modulation (laser beam, microwave electromagnetic field, etc. ). The present book deals with parametric wave turbulence.

Macroscopic objects made of magnetic materials have been known to mankind for several thousand years and are widely used in various fields of human activity. With the development and practical implementation of microelectronics, and more recently nanoelectronics, it has become possible to develop and manufacture magnetic nanomaterials, dramatically expanding the scope of magnetics in modern technologies. Today, magnetic nanomaterials and nanostructures are key components of advanced information technologies. They are widely used in eMobility, medicine, sensors, robotics, etc., and have significant potential for application in prospective smart wearables and human-machine interfaces. This volume outlines recent research in the field of functional magnetic and spintronic materials. Each of the 10 chapters in the volume is self-contained, allowing the topics to be explored independently of the material in other chapters. The book covers the entire “life cycle” of magnetic/spintronic nanomaterials: from theoretical and numerical studies of their properties (Ch. 1), fabrication and experimental study of film systems (Ch. 2), fabrication of nanostructures (Ch. 3), study of electromagnetic phenomena occurring in such nanostructures (Chs. 4-10), to the use of these nanostructures in new technologies, particularly in spintronic energy harvesting (Ch. 9) and quantum sensing (Ch. 10). Some of the contributions to this volume were presented as lectures and reports at the Advanced Research Workshop “Functional Spintronic Nanomaterials for Radiation Detection and Energy Harvesting” (25–27 September 2023, Kyiv, Ukraine), which was supported by the NATO Science for Peace and Security Programme.

Spintronics Handbook, Second Edition offers an update on the single most comprehensive survey of the two intertwined fields of spintronics and magnetism, covering the diverse array of materials and structures, including silicon, organic semiconductors, carbon nanotubes, graphene, and engineered nanostructures. It focuses on seminal pioneering work, together with the latest in cutting-edge advances, notably extended discussion of two-dimensional materials beyond graphene, topological insulators, skyrmions, and molecular spintronics. The main sections cover physical phenomena, spin-dependent tunneling, control of spin and magnetism in semiconductors, and spin-based applications.

Frontiers in Magnetism of Reduced Dimension Systems presents a definitive statement of our current knowledge and the state of the art in a field that has yet to achieve maturity, even though there are a number of potential applications of thin magnetic films and multilayers, such as magnetic sensors, data storage/retrieval media, actuators, etc. The book is organized into 13 chapters, each including a lecture and contributed papers on a similar subject. Five chapters deal with theoretical descriptions of electron transport phenomena, relaxation processes, nonlinear paramagnetic interactions, phase transitions and macroscopic quantum effects in magnetic films and particles. The description of different characterization techniques occupies an important place in the book. Separate chapters are dedicated to magnetic resonances (FMR, SWR, NMR), magneto-optical spectroscopy, controlling chaos, magnetoelastic phenomena and magnetic resonance force microscopy. A further chapter gives a detailed review, spread over a number of papers, of materials in current use in information storage devices.

This book presents recent scientific achievements in the investigation of magnetization dynamics in confined magnetic systems. Introduced by Bloch as plane waves of magnetization in unconfined ferromagnets, spin waves currently play an important role for description of very small systems.Spin wave confinement effect was experimentally discovered in the 1990s in permalloy microstripes. The diversity of systems where this effect is observed has been steadily growing since then, most of which will be addressed in this book. The book includes six chapters which originate from different groups of experimentalists and theoreticians dominating the field since the discovery of the effect. Different chapters of the book reflect different facets of spin wave confinement, providing a comprehensive description of the effect and its place in modern magnetism. It will be of value for scientists and engineers working on magnetic storage elements and magnetic logic, and is also suitable as an advanced textbook for graduate students.

In the past 30 years, magnetic research has been dominated by the question of how surfaces and interfaces influence the magnetic and transport properties of nanostructures, thin films and multilayers. The research has been particularly important in the magnetic recording industry where the giant magnetoresistance effect led to a new generation of storage devices including hand-held memories such as those found in the ipod. More recently, transfer of spin angular momentum across interfaces has opened a new field for high frequency applications.This book gives a comprehensive view of research at the forefront of these fields. The frontier is expanding through dynamic exchange between theory and experiment. Contributions have been chosen to reflect this, giving the reader a unified overview of the topic. - Addresses both theory and experiment that are vital for gaining an essential understanding of topics at the interface between magnetism and materials science - Chapters written by experts provide great insights into complex material - Discusses fundamental background material and state-of-the-art applications, serving as an indispensable guide for students and professionals at all levels of expertise - Stresses interdisciplinary aspects of the field, including physics, chemistry, nanocharacterization, and materials science - Combines basic materials with applications, thus widening the scope of the book and its readership
