DC-current induced domain wall in a chiral -wave superconductor
We study theoretically the impact of an applied DC-current on a mesoscopic
chiral -wave superconductor. Performing quasiclassical calculations on a
two-dimensional system, with an external magnetic flux to generate a DC
current, we show that the current can trigger a transition to a state with a
domain wall between regions of different chiralities. The system shows an
hysteretic behavior, as different domain wall configurations are possible for a
given current. This domain wall creation mechanism can give new insights on
recent experiments observing anomalous current variations in SrRuO
junctions.Comment: 7 pages, 3 figure
