On the anisotropy of -vector in SrRuO

Nomura, Takuji; Ikeda, Hiroaki*

Anisotropy of -vector in a spin-triplet superconductor SrRuO is discussed, by solving the linearized Eliashberg equation for a multi-band Hubbard model and a dp-model. Here the effective pairing interaction is calculated by expanding perturbatively to third order in the onsite Coulomb interaction. It is shown that the Eu state () is stabilized in the case of small spin-orbit interaction, consistent with experimental results.
