Penetration of nonintegral magnetic flux through a domain-wall bend in time-reversal symmetry broken superconductors
Penetration of nonintegral magnetic flux through a domain-wall bend in time-reversal symmetry broken superconductors
It has been proposed that the superconductivity of Sr$_2$RuO$_4$ is characterized by pairing that is unconventional and, furthermore, spontaneously breaks time-reversal symmetry. However, one of the key expected consequences, viz., that the ground state should exhibit chiral charge currents localized near the boundaries of the sample, has not been observed, …
