本文综述了静态和动态界面效应在磁性，重点是界面驱动的磁效应和现象与自旋轨道耦合和内在对称性破缺的接口。它提供了一个历史背景和文献调查，但重点是最近的进展，确定最令人兴奋的新的科学成果，并指出有前途的未来研究方向。它首先介绍和概述了界面如何影响基本的磁特性，然后讨论了通过界面和界面附近的电荷和自旋输运，以及如何使用这些来控制磁性层的特性。重要的概念包括自旋累积、自旋流、自旋转移矩和自旋泵。概述了目前的知识状态和现有的审查文献的界面效应，如交换偏置，交换弹簧磁铁，自旋霍尔效应，氧化物异质结构，拓扑绝缘体。本文重点介绍了最近发现的界面诱导磁性和非共线自旋织构，非线性动力学，包括自旋转移力矩和磁化反转的界面，界面效应在超快磁化过程中。
This article reviews static and dynamic interfacial effects in magnetism, focusing on interfacially driven magnetic effects and phenomena associated with spin-orbit coupling and intrinsic symmetry breaking at interfaces. It provides a historical background and literature survey, but focuses on recent progress, identifying the most exciting new scientific results and pointing to promising future research directions. It starts with an introduction and overview of how basic magnetic properties are affected by interfaces, then turns to a discussion of charge and spin transport through and near interfaces and how these can be used to control the properties of the magnetic layer. Important concepts include spin accumulation, spin currents, spin-transfer torque, and spin pumping. An overview is provided to the current state of knowledge and existing review literature on interfacial effects such as exchange bias, exchange-spring magnets, the spin Hall effect, oxide heterostructures, and topological insulators. The article highlights recent discoveries of interface-induced magnetism and noncollinear spin textures, nonlinear dynamics including spin-transfer torque and magnetization reversal induced by interfaces, and interfacial effects in ultrafast magnetization processes.
