Scaling and data collapse in magnetic viscosity (creep) of superconductors

This paper presents experimental evidence for scaling and data collapse of the magnetic viscosity (creep) coefficient for type II superconductors. It is demonstrated that, by using appropriate scaling, the creep coefficient v ersus magnetic field curves observed at different temperatures collapse ont o one "universal" curve. This data collapse suggests a peculiar self-simila r structure of the creep coefficient as a function of two variables: magnet ic held and temperature.
