  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.
