Spontaneous time reversal and parity breaking in a $d_{x^2-y^2}$-wave superconductor with magnetic impurities

Abstract

It is argued that the $d_{x^2-y^2}$ superconductor exhibits the transition into $d_{x^2-y^2}+i{d}_{xy}$ state in the presence of magnetic impurities in certain conditions. Linear coupling between impurity magnetization and the $d_{xy}$ component drives this transition. Violation of time-reversal symmetry and parity occurs spontaneously via the second order transition. In the ordered phase both impurity magnetization and $d_{xy}$ component of the order parameter develop and are proportional to each other.
