Effect Of Flux-Creep On The Temperature-Dependence Of The Current-Density In Y-Ba-Cu-O Crystals
PHYSICAL REVIEW B(1993)
摘要
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.
