Описание: This book focuses on the characterisation of the chiral and topological nature of magnetic skyrmions in noncentrosymmetric helimagnets. In these materials, the skyrmion lattice phase appears as a long-range-ordered, close-packed grid of nearly millimetre-level correlation length, while the size of a single skyrmion is 3–100 nm. This is a very challenging range of length scales (spanning 5 orders of magnitude from tens of nm to mm) for magnetic characterisation techniques, and, to date, extensive information on this fascinating, magnetically ordered state has remained elusive. In response, this work develops novel resonant elastic x-ray scattering (REXS) techniques, which allow the magnetic structure, including the long-range order and domain formation, as well as microscopic skyrmion parameters, to be measured across the full range of length scales. Most importantly, using circular dichroism in REXS, the internal structure of a given skyrmion, the topological winding number, and the skyrmion helicity angle can all be unambiguously determined. These new techniques are applicable to many materials systems, and allow us to retrieve information on modulated spin structures, multiferroic order, spin-density-waves, and other forms of topological magnetic order.
Описание: This book provides extensive and novel insights into transport phenomena in MnSi, paving the way for applying the topology and chirality of spin textures to the development of spintronics devices. In particular, it describes in detail the key measurements, e.g. magnetoresistance and nonlinear electronic transport, and multiple material-fabrication techniques based on molecular beam epitaxy, ion-beam microfabrication and micromagnetic simulation.The book also reviews key aspects of B20-type MnSi chiral magnets, which host magnetic skyrmions, nanoscale objects formed by helical spatial spin structures. Readers are then introduced to cutting-edge findings on the material. Furthermore, by reviewing the author’s successful experiments, the book provides readers with a valuable update on the latest achievements in the measurement and fabrication of magnetic materials in spintronics.

Описание: Ferroic materials are important, not only because of the improved understanding of condensed matter, but also because of their present and potential device applications. This book presents a unified description of ferroic materials at an introductory level, with the unifying factor being the occurrence of nondisruptive phase transitions in crystals that alter point-group symmetry. The book also aims to further systemitize the subject of ferroic materials, employing some formal, carefully worded, definitions and classification schemes. The basic physical principles leading to the wide-ranging applications of ferroic materials are also explained, while placing extra emphasis on the utilitarian role of symmetry in materials science.

Описание:
Magnetic skyrmions are particle-like objects described by localized solutions of non-linear partial differential equations. Up until a few decades ago, it was believed that magnetic skyrmions only existed in condensed matter as short-term excitations that would quickly collapse into linear singularities. The contrary was proven theoretically in 1989 and evidentially in 2009. It is now known that skyrmions can exist as long-living metastable configurations in low-symmetry condensed matter systems with broken mirror symmetry, increasing the potential applications possible. Magnetic Skyrmions and their Applications delves into the fundamental principles and most recent research and developments surrounding these unique magnetic particles.
Despite achievements in the synthesis of systems stabilizing chiral magnetic skyrmions and the variety of experimental investigations and numerical calculations, there have not been many summaries of the fundamental physical principles governing magnetic skyrmions or integrating those concepts with methods of detection, characterization and potential applications. Magnetic Skyrmions and their Applications delivers a coherent, state-of-the-art discussion on the current knowledge and potential applications of magnetic skyrmions in magnetic materials and device applications.
First the book reviews key concepts such as topology, magnetism and materials for magnetic skyrmions. Then, charactization methods, physical mechanisms, and emerging applications are discussed.
Covers background knowledge and details the basic principles of magnetic skyrmions, including materials, characterization, statics and dynamics
Reviews materials for skyrmion stabilization including bulk materials and interface-dominated multilayer materials
Describes both well-known and unconventional applications of magnetic skyrmions, such as memristors and reservoir computing

Описание: This book provides a comprehensive introduction to ferroics and frustrated materials. Ferroics comprise a range of materials classes with functionalities such as magnetism, polarization, and orbital degrees of freedom and strain. Frustration, due to geometrical constraints, and disorder, due to chemical and/or structural inhomogeneities, can lead to glassy behavior, which has either been directly observed or inferred in a range of materials classes from model systems such as artificial spin ice, shape memory alloys, and ferroelectrics to electronically functional materials such as manganites. Interesting and unusual properties are found to be associated with these glasses and have potential for novel applications. Just as in prototypical spin glass and structural glasses, the elements of frustration and disorder lead to non-ergodocity, history dependence, frequency dependent relaxation behavior, and the presence of inhomogeneous nano clusters or domains. In addition, there are new states of matter, such as spin ice; however, it is still an open question as to whether these systems belong to the same family or universality class.The purpose of this work is to collect in a single volume the range of materials systems with differing functionalities that show many of the common characteristics of geometrical frustration, where interacting degrees of freedom do not fit in a lattice or medium, and glassy behavior is accompanied by additional presence of disorder. The chapters are written by experts in their fields and span experiment and theory, as well as simulations. Frustrated Materials and Ferroic Glasses will be of interest to a wide range of readers in condensed matter physics and materials science.
