Аннотация

The results of the experimental determination of the spin Hall angle in a two-layer metal/ferromagnet structure Pt/La_0.7 Sr_0.3 MnO_3, obtained from the angular dependences of the longitudinal and transverse spin magnetoresistance in the planar Hall effect configuration are presented. The spin Hall angle determined from the longitudinal magnetoresistance was θ_Hx ≈ 0.016, and from transverse θ_Hy ≈ 0.018, while for SrIrO_3/La_0.7 Sr_0.3 MnO_3 heterostructures the ratio of the transverse to longitudinal spin Hall angle turned out to be significantly higher, θ_Hy/θ_Hx ≈ 9, which is most likely caused by the formation of a layer with high conductivity at the SrIrO_3 boundary /La_0.7 Sr_0.3 MnO_3.
