N2 - New measurements of critical current Ic in granular Al microbridges are presented. They show, near the critical temperature Tc, a departure from the mean-field behavior (linear dependence of Ic 2/3 on T). Enhancement of Ic by microwaves is simultaneously observed, up to Tc. The results point out to a Tc enhancement (by ~ 10mK). A numerical model, which depicts the shape of the Ic 2/3(T) curve, is presented. The model also explains the co-existence of microwave enhancement, and can account for non-linear Ic2/3(T) curves measured by others.2, 3
