- Title
Magnetic Flux Penetration into Superconductor in Vortex-Liquid and Vortex-Glass Regimes.

- Abstract
Magnetic flux penetration into a half-space occupied by a type-II superconductor occurring in a vortex-liquid or vortex-glass state is considered under the assumption that magnetic field exhibits a sharp increase with time (in the blow-up regime) at the interface. It is shown that each phase admits effective localization of magnetic flux in the form of a magnetic wave front, which is stopped at a depth of xs ∝ e–σσ in a vortex-liquid regime and at xs ∝ (2σ)1/(σ + 2) in a vortex-glass regime. Here, the parameter σ=U0/T depends on the thermal activation barrier height U0 and on the temperature T in the vicinity of the melting curve Tm(B) at a given magnetic field induction B. © 2005 Pleiades Publishing, Inc.
