Article Synopsis
- - Spintronic devices utilize two materials with differing magnetic and electronic properties, and an energy barrier that forms at their interface affects spin transport, which has not been thoroughly examined.
- - Research using diffusive spin Hall currents shows that this energy barrier plays a significant role in spin transport within metallic systems, particularly in NiFe/BiSb bilayers, where notable field-like torque was observed.
- - The study suggests that reducing work function differences in the heterostructure can enhance spin mixing conductance and spin-orbit torques, presenting a new way to manipulate spin transport through interfacial engineering.
We report the observation of magnetoresistance originating from Rashba spin-orbit coupling (SOC) in a metallic heterostructure: the Rashba-Edelstein (RE) magnetoresistance. We show that the simultaneous action of the direct and inverse RE effects in a Bi/Ag/CoFeB trilayer couples current-induced spin accumulation to the electric resistance. The electric resistance changes with the magnetic-field angle, reminiscent of the spin Hall magnetoresistance, despite the fact that bulk SOC is not responsible for the magnetoresistance.
