Relaxation under Supercooling of the Disordered Vortex State in Doped CeRu2 Alloy
M. K. Chattopadhyay, K. J. S. Sokhey, S. B. Roy +1
Relaxation in magnetisation of metastable states is reported. The states are prepared by supercooling a Ce(Ru, 5% Nd)2 alloy sample to different extents through similar paths in th…
Possibility of Kauzmann points in the vortex matter phase diagram of single crystal YBaCuO
S. B. Roy, Y. Radzyner, D. Giller +4
We highlight interesting thermomagnetic history effects across the transition line between the (quasi) ordered and disordered vortex states in single crystal YBaCuO…
Vortex Matter and its Phase Transitions
P. Chaddah, S. B. Roy
The mixed state of type II superconductors has magnetic flux penetrating the sample in the form of vortices, with each vortex carrying an identical quantum of flux. These vortices…
Metastabilities in vortex matter
P. Chaddah, S. B. Roy
We extend the classical theory for supercooling across first order phase transitions to the case when both density and temperature are control variables. The observable region of m…
