Percolation Transition in the Heterogeneous Vortex State in NbSe2
O. Dogru, E. Y. Andrei, M. J. Higgins +1
A percolation transition in the vortex state of a superconducting 2H-NbSe2 crystal is observed in the regime where vortices form a heterogeneous phase consisting of ordered and dis…
V-I characteristics in the vicinity of order-disorder transition in vortex matter
Y. Paltiel, Y. Myasoedov, E. Zeldov +5
The shape of the V-I characteristics leading to a peak in the differential resistance r_d=dV/dI in the vicinity of the order-disorder transition in NbSe2 is investigated. r_d is la…
Amorphization of Vortex Matter and Reentrant Peak Effect in YBaCuO
D. Pal, D. Dasgupta, B. K. Sarma +3
The peak effect (PE) has been observed in a twinned crystal of YBaCuO for Hc in the low field range, close to the zero field superconducting transition t…
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…
Peak Effect in CaRhSn : Vortex Phase Diagram and Evidences for Stepwise Amorphization of Flux Line Lattice
S. Sarkar, D. Pal, S. S. Banerjee +9
The Peak Effect (PE) regime in a single crystal of CaRhSn has been investigated in detail via ac susceptibility as well as dc magnetization measurements. The PE regi…
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…
