Critical Fluctuation Behavior in the Resistive Transition of Superconducting Bi Films
The electrical resistance of a superconducting metal decreases gradually at first and then at a rapidly increasing rate as the transition temperature T c is approached from above. Extensive agreement 1 has been found between film measurements made at temperatures sufficiently above T c . that the change in resistance does not exceed about one-quarter of the residual normal-state value R 0 and theories based on the presence above T c of fluctuation-produced Cooper electron pairs. These theories assume small concentrations of such carriers and so reasonably neglect interactions.
