Ideal resistive transition of a superconductor

Precise measurements of the change of conductivity with temperature have been made for stabilized amorphous bismuth films. The experiments indicate that the initial rapid change of conductivity at the superconducting transition depends on temperature as (T−T c) -2 3 . This extends over a temperature...

Description
Summary:Precise measurements of the change of conductivity with temperature have been made for stabilized amorphous bismuth films. The experiments indicate that the initial rapid change of conductivity at the superconducting transition depends on temperature as (T−T c) -2 3 . This extends over a temperature range of about 3 millidegrees. At higher temperatures the dependence is found to be ( T− T c) -1.
