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, spin Hall effect, oxide heterostructures, and topological insulators. The article highlights recent discoveries of interface-induced magnetism and non-collinear spin textures, non-linear dynamics including spin torque transfer and magnetization reversal induced by interfaces, and interfacial effects in ultrafast magnetization processes.
本文回顾了磁学中的静态和动态界面效应，重点关注界面驱动的磁效应以及与自旋轨道耦合和界面处固有对称性破缺相关的现象。它提供了历史背景和文献综述，但侧重于近期进展，识别最令人兴奋的新科学成果并指出有前景的未来研究方向。文章首先介绍和概述了基本磁性能如何受到界面的影响，然后转向讨论通过界面及在界面附近的电荷和自旋输运，以及如何利用这些来控制磁性层的性能。重要概念包括自旋积累、自旋电流、自旋转移矩和自旋泵浦。本文概述了关于界面效应（如交换偏置、交换弹簧磁体、自旋霍尔效应、氧化物异质结构和拓扑绝缘体）的当前知识状态和现有综述文献。文章突出了界面诱导磁性和非共线自旋纹理的近期发现、包括自旋扭矩转移和界面诱导的磁化反转在内的非线性动力学，以及超快磁化过程中的界面效应。
