Abstract :
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 versus magnetic field curves observed at different temperatures collapse onto one “universal” curve. This data collapse suggests a peculiar self-similar structure of the creep coefficient as a function of two variables: magnetic field and temperature
