摘要
The authors report here the self-induced inverse spin Hall effect in epitaxial La${}_{0.67}$Sr${}_{0.33}$MnO${}_{3}$ (LSMO) films and perform first-principles calculations of the spin Hall conductivities of bulk LSMO. The LSMO films were prepared using pulsed laser deposition. The spin pumping voltage ${V}_{s\phantom{\rule{0}{0ex}}p}$ dominates over spin rectification effects, indicating the presence of appreciable spin-to-charge conversion in LSMO films. The spin Hall conductivity is calculated from first principles using density functional theory and the Kubo formalism, and the results qualitatively match with the experimental findings.
