Resumo

This paper presents the results of experimental studies of the cross section of the boundaries of the SrIrO3/La0.7Sr0.3MnO3 и Pt/La0.7Sr0.3MnO3, heterostructures, in which, upon excitation of ferromagnetic resonance in a La0.7Sr0.3MnO3 film, a spin current arises that flows through the boundary in structure. Epitaxial growth of thin films of strontium iridate SrIrO3 and manganite La0.7Sr0.3MnO3 on a (110) NdGaO3 single-crystal substrate was carried out using magnetron sputtering at high temperature in a mixture of argon and oxygen gases. The spin mixing conductance, which determines the amplitude of the spin current and generally has real Re g↑↓ and imaginary Im g↑↓ parts, was determined from the frequency dependence of the FMR spectrum of the LSMO film and heterostructures. It is shown that the Im g↑↓ quantity, can play an important role in determining the spin Hall angle (θSH) from the angular dependence of the spin magnetoresistance. For the SrIrO3/La0.7Sr0.3MnO3 heterostructures, θSH turned out to be significantly higher (almost an order of magnitude) than for the Pt/La0.7Sr0.3MnO3 heterostructure.
