Abstract: The results of studies of ferromagnetic resonance (FMR) of iridate/manganite epitaxial heterostructures in a wide range of microwave frequencies (1 – 20 GHz) are presented. The magnitudes of imaginary and real parts of the spin mixing conductance of the heterostructure boundary determining the spin current were determined from the frequency dependence of the spin damping and changes in the resonance field of the FMR. It is shown that the value of the imaginary part of spin conductance is comparable to the real part, which may be caused by strong spin-orbit interaction occurring in 5d-oxides of transition metals (iridate).
Keywords: ferromagnetic resonance, SrIrO$_3$/La$_{0.7}$Sr$_{0.3}$MnO$_3$ heterostructures, spin current, spin mixing conductance.

The study was accomplished in the framework of State Assignment for Kotelnikov IRE of RAS. The study was performed by using the equipment of Unique Research Facility № 352529 “Cryointegral” whose development was supported by the grant of RF Ministry of Science and Higher Education (contract № 075-15-2021-667). Development of the microwave measurement technique by A.A. Klimov was supported by the Russian Scientific Foundation (project No 20-12-00276).
