Hysteresis of critical currents of superconducting bridges in a weak magnetic field

Critical currents of indium and niobium bridges with constant thickness as well as granular aluminum bridges with constant thickness show hysteresis in a weak perpendicular magnetic field. It is found that the critical currents are determined by the pair-breaking mechanism.
