Abstract :
In this work, the intrinsic vortex viscosity in several cuprates are determined. It is confirmed that in REBCO (SmBCO) film the vortex viscosity is consistent with a conventional framework based on the Bardeen-Stephen model. In TBCCO a significantly smaller viscosity is observed, and possible test to assess the nature of this new effect is suggested.
