Abstract
We observed hysteretic voltage‐current (VI) curves in superconducting tantalum thin films at zero magnetic field (B=0) at temperatures (T) below a characteristic temperature T*. This is in contrast to the Kosterlitz‐Thouless (KT) theory which expects continuous and reversible VI’s. We interpret that the hysteresis arises from the critical dynamics of self‐generated magnetic vortices, and map the area in B‐T plane where the VI’s are hysteretic.
