Spin Hall magnetoresistance of YIG / Pt with magnetic layer inserted into the interface

摘要

We have investigated the spin Seebeck voltage in the system of YIG / magnetic layer / Pt (5 nm) and reported that these voltages are large more than YIG / Pt (5 nm) . This is probably because the spin mixing conductance was improved by inserting the magnetic layer. In this research by measuring the spin Hall magnetoresistance (SMR), we discuss the improvement of the interface state by inserting the magnetic layer. In addition, by discussing the relationship with the spin Seebeck voltage, we also investigate the relations between interface state and the electromotive force.
