Abstract
The superconducting transition was studied in Al wire networks with built-in positional disorder. Application of small transverse magnetic fields increased the mean-field critical temperature in the disordered networks but not in the ordered networks. The magnitude of this Tc enhancement was independent of changes in bias current, probe separation, and measurement configuration, unlike the apparent Tc shifts associated with nonequilibrium resistance anomalies previously observed in superconducting microstructures.
