Аннотация:The temperature dependence of the voltage induced by spin current is studied in the epitaxial thin-film La0.7Sr0.3MnO3/SrIrO3 heterostructure deposited on a single-crystal NdGaO3 substrate. The spin cur-rent is generated during microwave pumping in conditions of the ferromagnetic resonance in aLa0.7Sr0.3MnO3 ferromagnetic film and is registered in a SrIrO3 film due to the inverse spin Hall effect. Thespin current spectrum half-width increases significantly and the spin current amplitude increases on coolingfrom room temperature (300 K) to 135 K.
