“…To date, significant focus has been set on NM/FM heterostructures comprising 3d materials 5-8 with a recent extension to yttrium iron garnet (YIG). [9][10][11] Further identification of new material platforms for the efficient generation, transmission, and conversion of spin currents is of great importance for enriching this emerging field.…”

We report ferromagnetic resonance measurements of magnetic anisotropy and damping in epitaxial La0.7Sr0.3MnO3 (LSMO) and Pt capped LSMO thin films on SrTiO3 (001) substrates. The measurements reveal large negative perpendicular magnetic anisotropy and a weaker uniaxial in-plane anisotropy that are unaffected by the Pt cap. The Gilbert damping of the bare LSMO films is found to be low α = 1.9(1) × 10−3, and two-magnon scattering is determined to be significant and strongly anisotropic. The Pt cap increases the damping by 50% due to spin pumping, which is also directly detected via inverse spin Hall effect in Pt. Our work demonstrates efficient spin transport across the Pt/LSMO interface.

“…Ferromagnetic resonance (FMR) spin pumping of pure spin currents from a ferromagnet (FM) into a nonmagnetic (NM) material provides a powerful technique for measurement of θ SH in a broad range of materials [7,9]. We report a systematic study of the ISHE in a series of 3d transition metals using FMR spin pumping from Y 3 Fe 5 O 12 (YIG) epitaxial films into Ti, V, Cr, Mn, Fe 50 Mn 50 (FeMn), Fe 20 Ni 80 (Py), Ni, and Cu.…”

“…It is generally believed that SOC varies as Z 4 [5][6][7], implying that SOC is important only in heavy elements, while in lighter elements such as 3d transition metals, SOC should be negligibly small. SHE depends on the SOC and θ SH is a measure of the strength of SOC.…”

The large ISHE signals in our YIG-based structures [7,15,[18][19][20][21] provides unprecedented sensitivity for characterizing the ISHE in 3d metals which are expected to have weak SOC. Surprisingly, we detect an ISHE voltage (V ISHE ) exceeding 5 mV in a YIG/Cr(5 nm) bilayer, which is among the highest V ISHE we observed in any materials [7,15].…”
