Abstract
Interfaces determine spin transfer efficiency of magnetic heterostructures. Here, the authors study spin pumping at the YIG/Pt interface, together with an atomic-scale investigation of interfacial magnetic states. This work singles out the structural, chemical, and magnetic states at the interface and clearly reveals their different roles in spin pumping, especially the critical role of the interfacial magnetic moments on spin mixing conductance at the interface, providing a guide to optimize future spintronics devices.
