Vortex Dynamics in Lightly-Doped Films of High Temperature Superconductors

Abstract

Evidence is presented supporting the view that the inductance of vortices in films is due to columnar defects. The temperature dependence of the pinning strength is dominated by thermal supercurrent or "phase" fluctuations rather than by the mean-field temperature dependence of basic superconducting quantities like the Helmholtz free energy and the magnetic penetration depth.
