Superconducting phases in strontium ruthenate

Abstract

We review our recent work concerning the search for the superconducting state realised in Sr 2 RuO 4 . The orbital symmetry of the order parameter in this spin triplet superconductor is widely believed to be chiral one with d-vector along the crystal c-axis. The three band, three dimensional model with two different phenomenological interaction parameters is able to explain most of the existing data in quantitative way. This is also true for the recently observed "rotation" of the d-vector in magnetic field directed along c-axis.
