The Pair-Field Susceptibility of Superconductors
Recent experimental1,2 and theoretical work3–5 has shown that the susceptibility associated with the superconducting transition can be determined in a simple dc tunneling experiment. Both Scalapino4 and Takayama5 have presented detailed calculations of an excess current due to pair tunneling in superconductor-insulator normal metal junctions. This current is a measure of the susceptibility in the normal metal. In the following we present the extent of agreement between experiment and theory and indicate areas where further work should be pursued.
