Abstract

Spin pumping across interfaces between metallic SrVO3, where V is a 3d1 ion, epitaxial thin films and ferromagnetic Ni80Fe20 is reported. Data shows an efficient spin pumping with a spin mixing conductance value (g↑↓ = 11.8 × 1018 m− 2 ) similar to that reported in metallic Vanadium but significantly larger than that measured in isoelectronic (3d1 ) VO2, which displays a Mott transition. Data are rationalized in terms of the relevance of density of states at the Fermi level and the relative strength of electron-electron correlations and electron-lattice coupling as toggles to tune spin-mixing conductance across interfaces.
