Description
Summary:The results of advanced research in the developing field of modern magnetism and spintronics, namely, topological nanomagnetism, in the framework of which the nature of the nontrivial spin textures and topological effects is studied, are reported. Most attention is paid to chiral spin textures that are recently discovered in thin magnetic films, such as skyrmions, skyrmioniums, antiskyrmions, and others, as well as to their static and dynamic properties, methods for their generation and control, and the prospects for creating functional devices based on them. Interest in one-, two-, and three-dimensional magnetic structures is driven not only by the range of new properties and effects that require further theoretical and experimental studies, but also by the potential for their applications in practice. The possibility of generating small and stable magnetic textures, such as skyrmions, opens up prospects for creating new types of random access memory and configurable logic, and for developing neuromorphic computation systems.
