Guest Editorial: Special Issue on Spin Pumping and Spin-Orbit Torques in Magnetic Heterostructures

Abstract

Spin pumping and spin-orbit torques play important roles in advancing spintronic device technologies. Our curated special issue focuses on these phenomena in magnetic heterostructures, which are critical for various applications. The high-quality papers 1 , 2 , 3 , 4 , 5 , 6 , 7 delve into spin pumping and spin-orbit torques in diverse heterostructures, addressing topics such as insulating/metallic interfaces tailoring spin-to-charge conversion, the influence of HfOx capping layers on perpendicular magnetic anisotropy, anisotropy-controlled spin current generation, sputter pressure-dependent spin Hall angle, the effect of oxygen ion irradiation on spin-orbit torques, and a review paper of emerging two-dimensional/ferromagnetic interfaces. This Editorial discusses the reported articles and the future perspective of these topics. With this special issue, we anticipate significant contributions to both academic research and industrial developments in this direction.
