Abstract

We have performed transport and tunneling density of states measurements of ultra-thin Al films through The first-order parallel critical field transition. The transition is intrinsically hysteretic and exhibits avalanche-like jumps in both resistivity and tunneling density states. Tunneling measurements on films with sheet resistances of a few hundred ohms show large avalanche-like collapses of The condensate on The superheating branch of The critical field hysteresis loop. In contrast, The transition back into The superconducting phase (i.e., along The supercooling branch) is always continuous.
