First-Order Melting and Dynamics of Flux Lines in a Model for YBa2Cu3O7−δ
We have studied the statics and dynamics of flux lines in a model for YBa2Cu3O7−δ , using both Monte Carlo simulations and Langevin dynamics. The lines are assumed to be flexible but unbroken in both the solid and liquid states. For a clean system, both approaches yield the same melting curve, which is found to be weakly first order with a heat of fusion of about 0.02kBTm per vortex pancake at ...

We propose a phase diagram for the vortex structure of high temperature superconductors which incorporates the effects of anisotropy and disorder. It is based on numerical simulations using the three-dimensional Josephson junction array model. We support the results with an estimation of the internal energy and configurational entropy of the system. Our results give a unified picture of the beh...

متن کاملCurrent-driven vortex dynamics in untwinned YBa2Cu3O7 superconducting single crystals
Current-driven vortex dynamics of type-II superconductors in the weak-pinning limit is investigated by quantitatively studying the current-dependent vortex dissipation of an untwinned YBa2Cu3O7 single crystal. For applied current densities (J ) substantially larger than the critical current density (Jc), non-linear resistive peaks appear below the thermodynamic firstorder vortex-lattice melting...
