Fluctuation-Induced Diamagnetism in Bulk Al and Al Alloys above the Superconducting Transition Temperature

Abstract

Fluctuations in the superconducting order parameter are supposed to lead to a precursor diamagnetic response at temperatures well above the transition temperature T. We have measured this effect in Al and some dilute Al alloys, a case which provides unique advantages for testing the predictions of current theories. We have also checked a recent report of results suggesting atypical behavior in Al.
