Stable and Metastable vortex states and the first order transition across the peak effect region in weakly pinned 2 H - NbSe
نویسندگان
چکیده
The peak effect in weakly pinned superconductors is accompanied by metastable vortex states. Each metastable vortex configuration is characterized by a different critical current density Jc, which mainly depends on the past thermomagnetic history of the superconductor. A recent model [G. Ravikumar et al, Phys. Rev. B 61, R6479 (2000)] proposed to explain the

Disordering of the vortex lattice through successive destruction of positional and orientational order in a weakly pinned Co0.0075NbSe2 single crystal
The vortex lattice in a Type II superconductor provides a versatile model system to investigate the order-disorder transition in a periodic medium in the presence of random pinning. Here, using scanning tunnelling spectroscopy in a weakly pinned Co(0.0075)NbSe(2) single crystal, we show that the vortex lattice in a 3-dimensional superconductor disorders through successive destruction of positio...
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...
متن کاملNature of the Order-disorder Transition of the Vortex Matter in Weakly Pinned Superconductors
Peak effect in weakly pinned superconductors represents order-disorder transition of the vortex matter. It is accompanied by metastability. Experimental manifestation of the metastability is highlighted and is explained by proposing a phenomenological model, in which each metastable vortex state corresponds to a distinct critical current density J c . Existence of a unique stable state correspo...
متن کاملPhase 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 کامل0 Instabilities and disorder - driven first - order transition of the vortex lattice
Transport studies in a Corbino disk geometry suggest that the Bragg glass phase undergoes a first-order transition into a disordered solid. This transition shows a sharp reentrant behavior at low fields. In contrast, in the conventional strip configuration, the phase transition is obscured by the injection of the disordered vortices through the sample edges, which results in the commonly observ...
