Determination of relaxation time in bulk superconductors

· Phys. Rev. Lett.; (United States)
A method for studying nonequilibrium effects and their k-bar-space anisotropy in bulk superconductors near T/sub c/ is reported. The relaxation time in single-crystal in determined directly by this method, tau (t) = 0.77 x 10/sup -10/(1-t)/sup -1///sup 2/, represents confirmation, both in form and magnitude, of the Schmid-Schoen predictions for the relaxation of the magnitude of the order parameter near the T/sub c/. The associated electron-phonon inelastic scattering time is in excellent agreement with that determined for the comparable portion of k space by cyclotron resonance.
