Spin-charge conversion requires materials with a large spin-orbit coupling, which is typically obtained in heavy metal (Pt, etc.) ions. Here we demonstrate spin pumping across interfaces between metallic SrVO3, where V is a 3d1 ion, epitaxial thin films and ferromagnetic Ni80Fe20.
Data shows an efficient spin pumping with a spin mixing conductance value (11.8 × 1018 m−2). These results demonstrate that heavy ions are not longer required and illustrated an yet undisclosed relevance of density of states at the Fermi level and suggest new toggles to tune spin-mixing conductance across interfaces.
