Current--voltage characteristics of NbSe/sub 2/ superconducting microbridges

The current--voltage characteristics of NbSe/sub 2/ superconducting microbridges were studied experimentally. A hysteresis of critical currents has been found in the current-voltage characteristics of microbridges larger than 5 x 10 x 1 ..mu..m in size, while no hysteresis but anomalies in the form of a time-dependent and field-dependent voltage have been found in the case of microbridges not larger than 5 x 10 x 1 ..mu..m.
