Comparative determination of Y3Fe5O12/Pt interfacial spin mixing conductance by spin-Hall magnetoresistance and spin pumping
Abstract
In this paper, we studied spin Hall magnetoresistance (SMR) in a Y3Fe5O12/Pt bilayer at room temperature. The SMR loops precisely follow the magnetization hysteresis loops in both the in-plane and out-of-plane configurations. SMR up to 0.09% is observed, from which an interfacial spin mixing conductance = (9.0 ± 2.6) × 1018 m-2 is extracted. In addition, we measured ferromagnetic resonance spin pumping induced damping enhancement in the bilayer, which gives = (6.9 ± 0.6) × 1018 m-2. Finally, the agreement in the values of obtained from two reciprocal processes within uncertainty demonstrates the validity of the model for analyzing interfacial spin transmission.
