Evaluation of Spin Hall Effect in Ferromagnets by Means of Unidirectional Spin Hall Magnetoresistance in Ta/Co Bilayers Open
We investigate unidirectional spin Hall magnetoresistance (USMR) in Ta/Co bilayer systems with various Co thicknesses. A negative USMR is observed when the thickness of Co is thin due to the negative spin Hall angle of Ta, as expected from…
