Triplet Pairing Superconductivity Induced by Short-Range Ferromagnetic Correlations in Sr${}_2$RuO${}_4$

K. Hoshihara, K. Miyake

The microscopic origin of triplet superconductivity in Sr${}_2$RuO${}_4$ is discussed, paying attention to the role of Coulomb interaction, $U_{pp}$, at the O site. It is shown on the…
