Experimental verification of the inverse Anomalous spin Hall effect with perpendicular magnetic anisotropy Materials (2312.06819v1)
Published 11 Dec 2023 in cond-mat.mes-hall and cond-mat.mtrl-sci
Abstract: In this work, the spin pumping technique was employed to investigate the anomalous inverse spin Hall effect in BIG/NiO/Fe samples where BIG[(Bi,Tm)3(Fe,Ga)5O12] exhibits perpendicular magnetic anisotropy. Our results reveal an intriguing phenomenon: when the magnetizations of both ferromagnetic layers align perpendicularly, a distinct spin-to-charge current conversion mechanism occurs. This conversion is intricately linked to the magnetization of the converting layer, spin polarization, and the spin current orientation.
