Experimental verification of the inverse anomalous spin Hall effect with perpendicular magnetic anisotropy materials

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 ) 5 O 12] exhibits perpendicular magnetic anisotropy. Our results reveal an intriguing phenomenon: when the magnetization of both ferro...

description 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 ) 5 O 12] exhibits perpendicular magnetic anisotropy. Our results reveal an intriguing phenomenon: when the magnetization of both ferromagnetic layers is perpendicular to each other, 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.
