Abstract
We present results on experimental determination of spin-Hall angle theta_SH in the SrIrO3/La0.7Sr0.3MnO3 heterostructure with nanometer-thick films. From longitudinal magnetoresistance value of spin-Hall angle was estimated thetaL_SH ≈ 0.04 ± 0.01, from the transverse thetaT_SH ≈0.35±0.06. Decreasing the temperature from room to T= 165 K, the transverse magnetoresistance decreased, and at temperatures T<150 K it was not detected within the measurement error. For comparison, we measured also a single SrIrO3 film which did not demonstrate magnetoresistance.
