    Abstract

    To understand the vortex states in Sr2RuO4, we investigate differences of the vortex structure for two chiral pairings px ± ipy, using quasi-classical Eilenberger theory and the Ginzburg-Landau theory. The induced opposite chiral component of the pair potential plays an important role in the vortex structure. It produces an √H-behavior of the zero-energy density of states at higher field. We also consider the anisotropic case of the Fermi surface and superconducting gap.
