Abstract

We report results of an investigation of magnetic-field dependent critical currents in artificially disordered superconducting Al wire networks well below Tc. Aperiodic but reproducible variations with field are found, in sharp contrast with the periodic oscillations observed close to Tc. Critical currents also exhibited strong variations on cycling the current at low fields reflecting variations in frozen-in metastable vortex patterns. Both the variations in field and on cycling vanished above a critical field set by the disorder strength.
