Abstract
Kotel'nikov Institute of Radioengineering and Electronics of Russian Academy of Sciences The results of experimental studies on spin current at the interface of iridate/manganite heterostructure SrIrO3/La0.7Sr0.3MnO3 consisted of oxide epitaxial films with nanometer thickness are presented. A pure spin current was induced by microwave irradiation in GHz frequency band under conditions of ferromagnetic resonance. The spin current was detected due to inverse spin-Hall effect measuring the spectral characteristics of charge current arising on electrically conductive SrIrO3 film with strong spin-orbit interaction. The spin-Hall angle, which characterizes the efficiency of spin current conversion to the charge current, was determined by measurements of the angular dependences of spin magnetoresistance of the iridate/manganite interface.
