Spin Magnetoresistance of Thin-Film Structures Made of Manganite and Material with Strong Spin-Orbital Interaction
Abstract—
The paper presents the results of experimental determination of the spin Hall angle in a Pt/La0.7Sr0.3MnO3 bilayer metal/ferromagnetic structure inferred from angular dependences of longitudinal and transverse spin magnetoresistance in configuration of the planar Hall effect. The value of the spin Hall angle determined from the longitudinal magnetoresistance is θHx ≈ 0.016, and that from the transverse magnetoresistance is θHy ≈ 0.018, whereas for SrIrO3/La0.7Sr0.3MnO3 heterostructures the ratio of values of the transverse spin Hall angle to the longitudinal one appears to be substantially higher, θHy/θHx ≈ 9, which is apparently caused by a layer with a high spin conductance formed at the SrIrO3/La0.7Sr0.3MnO3 interface.
