Effect of flux creep on the temperature dependence of the current density in Y-Ba-Cu-O crystals
Abstract
Temperature-dependent critical current density and normalized flux-creep rate, together with the current dependence of the vortex pinning energy, were studied in as-grown and proton-irradiated Y-Ba-Cu-O crystals. A consistent interpretation is found within the collective-pinning or vortex-glass models. © 1993 The American Physical Society.
