Effects of spin-flip scattering on the dynamics of the superconducting order parameter

Description

Measurements of the imaginary part of the pair-field susceptibility X'' have been carried out on dirty-limit Al-Er alloy films. Aluminum films with erbium concentrations of up to one atomic percent were incorporated as the low T/sub c/ film of an asymmetric Josephson junction. The excess current I/sub ex/ due to pair tunneling was measured as a function of the bias voltage V and of the magnetic field H, applied in the plane of the junction, at temperatures within 20% of the critical temperature T/sub c/. Comparison to theory was facilitated by noting that X''(..omega..,k) varies as I/sub ex/(V,H) where the ... continued below
