Abstract

Understanding the magnetic interactions is of fundamental importance in condensed-matter physics as well as in the application of spintronic devices. In the past 13 years, the Dzyaloshinskii–Moriya interaction (DMI) has attracted increasing attention, as it can trigger topological chiral magnetism, such as magnetic skyrmions, which is of particular interest from both fundamental and applied points of view. First-principles calculations have played an essential role in figuring out the microscopic properties of DMI and helped to search for the materials with strong DMI. In this Technical Review, we present a comprehensive and systematic survey of the first-principles-calculations methods for DMI, along with an overview of the first-principles calculations of the DMI properties of typical material systems and the DMI-induced magnetic phenomena. The Dzyaloshinskii–Moriya interaction is an exchange coupling that appears in magnetic systems with spin–orbit coupling. This Technical Review systematically surveys first-principles-calculations methods for DMI in different material systems and for a range of induced magnetic phenomena.

Dzyaloshinskii-Moriya相互作用的第一性原理计算

了解磁相互作用对凝聚态物理以及自旋电子器件的应用具有根本性的重要意义。在过去的 13 年中，Dzyaloshinski-Moriya 相互作用（DMI）引起了越来越多的关注，因为它可以引发拓扑手性磁性，如磁性天幕，这在基础和应用方面都具有特别的意义。第一性原理计算在弄清 DMI 的微观特性方面发挥了重要作用，并有助于寻找具有强 DMI 的材料。在这篇技术综述中，我们全面系统地介绍了 DMI 的第一性原理计算方法，并概述了典型材料体系的 DMI 特性和 DMI 引发的磁现象的第一性原理计算。Dzyaloshinskii-Moriya 相互作用是一种交换耦合，出现在具有自旋轨道耦合的磁性系统中。本技术综述系统地研究了不同材料体系中 DMI 的第一原理计算方法以及一系列诱导磁现象。
