Abstract

We present a first-principles study of spin-orbit coupling effects on the Fermi surface of Sr₂RuO₄ and Sr₂RhO₄. For nearly degenerate bands, spin-orbit coupling leads to a dramatic change of the Fermi surface with respect to nonrelativistic calculations; as evidenced by the comparison with experiments on Sr₂RhO₄, it cannot be disregarded. For Sr₂RuO₄, the Fermi surface modifications are more subtle but equally dramatic in the detail: Spin-orbit coupling induces a strong momentum dependence, normal to the RuO₂ planes, for both orbital and spin character of the low-energy electronic states. These findings have profound implications for the understanding of unconventional superconductivity in Sr₂RuO₄.
