✦ Synopsis

The critical current hysteresis of long Ag-Sn proximity-effect bridges, observed in the current-voltage characteristics obtained at helium bath temperatures T above and below the A point of helium T~, shows a jump discontinuity at T = TA. The relevance of the observed phenomenon to existing theories of superconductors driven into resistive states by direct currents is discussed.
