Abstract

The induction of an s-wave component in a d-wave superconductor is considered. Near the 110-oriented edges of such a sample, the induced s-wave order parameter together with d-wave component forms a complex combination d+eiϕ s, which breaks the time reversal symmetry (BTRS) of the pairing state. As a result, the spontaneous current is created. We numerically study the current distribution and the formation of the spontaneous flux induced by the current. We show that the spontaneous flux formed from a number of defect lines with 110 orientation has a measurable strength. This result may provide a unambiguous way to check the existence of BTRS pairing state at 110-oriented boundaries.
