Phase Diagram of weakly pinned YBa 2 Cu 3 O 7 − δ for H ‖ c
Abstract — Vortex phase diagram in a weakly pinned crystal of YBCO for H ‖ c is reviewed in the light of a recent elucidation of the process of ‘inverse melting’ in a Bismuth cuprate system and the imaging of an interface between the ordered and the disordered regions across the peak effect in 2HNbSe2. In the given YBCO crystal, a clear distinction can be made between the second magnetization p...
متن کاملEquilibrium phase diagram of a randomly pinned glass-former.
We use computer simulations to study the thermodynamic properties of a glass-former in which a fraction c of the particles has been permanently frozen. By thermodynamic integration, we determine the Kauzmann, or ideal glass transition, temperature [Formula: see text] at which the configurational entropy vanishes. This is done without resorting to any kind of extrapolation, i.e., [Formula: see t...
متن کاملVortex-Line Phase Diagram for Anisotropic Superconductors
The zero temperature vortex phase diagram for uniaxial anisotropic superconductors placed in an external magnetic field tilted with respect to the axis of anisotropy is studied for parameters typical of BSCCO and YBCO. The exact Gibbs free energy in the London approximation, using a self-energy expression with an anisotropic core cutoff, is minimized numerically, assuming only that the equilibr...
متن کاملNonequilibrium Dynamic Phase Diagram for Vortex Lattices
The new dynamic phase diagram for driven vortices with varying lattice softness we present here indicates that, at high driving currents, at least two distinct dynamic phases of flux flow appear depending on the vortex-vortex interaction strength. When the flux lattice is soft, the vortices flow in independently moving channels with smectic structure. For stiff flux lattices, adjacent channels ...
متن کاملDynamics of metastable vortex states in weakly pinned superconductors: A phenomenological model
We present a phenomenological model for the vortex dynamics in the peak effect region of weakly pinned superconductors. We explain the history dependent dynamic response of the metastable vortex states subjected to a transport current and the hysteretic voltage-current characteristics observed in the vicinity of peak effect in weakly pinned superconductors. A strong variation in voltage current...
