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…

Metastabilities across disorder-broadened first-order transitions

P. Chaddah

We discuss first-order phase transitions that are broadened by disorder, but still remain first order on the local mesoscopic level. Using vortex-matter as our paradigm, we argue t…

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…

Comment on ``Critical current density from magnetization hysteresis data using the critical-state model''

P. Chaddah

A recent paper [Physical Review {\bf B 64} 014508 (2001)] claims to present an exact method to extract the critical current density J from the M-H hysteresis curve. We show tha…

Peak effect in the vortex state of VSi: a study of history dependence

Sujeet Chaudhary, A. K. Rajarajan, Kanwal Jeet Singh +2

We present results of transport properties measurement on a single crystal of VSi showing distinct signature of peak-effect in its vortex state. The field variation of the elec…

Calculation of minor hysteresis loops under metastable to stable transformations in vortex matter

P. Chaddah, M. Manekar

We present a model in which metastable supercooled phase and stable equilibrium phase of vortex matter coexist in different regions of a sample. Minor hysteresis loops are calculat…
