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.
