The superconducting transition temperature is generally believed to be independent of the direction of applied small bias currents. Here, the authors demonstrate the occurrence of directional-dependent Berezinskii-Kosterlitz-Thouless transition at the two-dimensional superconducting interface EuO/KTaO3(111), which hints at emergent superconducting textures engendered by ferromagnetic proximity.
