Abstract

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.

磁性薄膜中的拓扑非平凡自旋织构

摘要

报告了现代磁性和自旋电子学发展领域的高级研究成果，即拓扑纳米磁性，在该框架中研究了非平凡自旋织构和拓扑效应的性质。最关注的是最近在薄磁性薄膜中发现的手性自旋纹理，例如skyrmions、skyrmionium、antiskyrmions等，以及它们的静态和动态特性、它们的产生和控制方法以及创造的前景基于它们的功能设备。对一维、二维和三维磁结构的兴趣不仅取决于需要进一步理论和实验研究的新特性和效果的范围，还取决于它们在实践中的应用潜力。
