Abstract:The nonlinear flux-flow behavior due to the nonequilibrium distribution of quasiparticles predicted by Larkin and Ovchinnikov has been observed in thin films of Al, In, and Sn. From the voltage-current characteristics the inelastic scattering time tauE of the electrons was obtained. For Al and In the values of tauE are in excellent agreement with the previous results. For Sn the value tauE=5×10–10 sec is slightly larger than the previous results.
