Abstract
The temperature dependence of the electromagnetic coherence length is calculated for superconductors in which the ratio of the zero-temperature energy-gap width to the critical temperature may differ from the BCS value. The calculation is based on the experimentally verified similarity principle that the ratio of the energy-gap width to its value at absolute zero is approximately a universal function of the reduced temperature .
