Perpendicular magnetic anisotropy at transition metal/oxide interfaces and applications

TLDR

In spintronics, magnetic materials act as polarizers or analyzers, and magnetic anisotropy determines the orientation of magnetization, influencing magnetic memory based on tunnel junctions and other spintronic applications. This review focuses on perpendicular magnetic anisotropy arising at magnetic metal/oxide interfaces. It analyzes the interfacial origins and effects of this anisotropy in metal/oxide systems.

Abstract

In spintronics devices, magnetic materials are used as polarizers or analyzers for electron spin. Magnetic anisotropy defines the orientation for magnetization and polarization of spin currents traversing the material. This review focuses on perpendicular magnetic anisotropy which arises at magnetic metal/oxide interfaces. This anisotropy plays a role in the magnetic memory based on magnetic tunnel junctions. Aspects of the anisotropy are described in various applications and in the field of spintronics research.
