Abstract
We have observed anomalously broad resistive transitions in superconducting films and have shown that the widths gradually reduce to the usual Aslamazov-Larkin value when a magnetic field is applied parallel to the film. These results are explained by adding to the Aslamazov-Larkin theory another fluctuation contribution to the conductivity of the type first proposed by Maki, which for thin films is logarithmically divergent with a cutoff proportional to the pair-breaking interactions.Keywords
