Instabilities and disorder-driven first-order transition of the vortex lattice
Y. Paltiel, E. Zeldov, Y. Myasoedov +8
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…
Stable and Metastable vortex states and the first order transition across the peak effect region in weakly pinned 2H-NbSe_2
G. Ravikumar, V. C. Sahni, A. K. Grover +6
The peak effect in weakly pinned superconductors is accompanied by metastable vortex states. Each metastable vortex configuration is characterized by a different critical current d…
Dynamic instabilities and memory effects in vortex matter
Y. Paltiel, E. Zeldov, Y. N. Myasoedov +7
Recent studies have shown a number of surprising vortex dynamics phenomena both in low and high temperature superconductors, which include: low frequency noise, slow voltage oscill…
A study of supercooling of the disordered vortex phase via minor hysteresis loops in 2H-NbSe_2
G. Ravikumar
We report on the observation of novel features in the minor hysteresis loops in a clean crystal of NbSe_2 which displays a peak effect. The observed behavior can be explained in te…
