Field induced first order antiferromagnetic to ferromagnetic transition in Al-doped CeFe: a calorimetric investigation
L. S. Sharath Chandra, Kaustav Mukherjee, V. Ganesan +4
Field variation of heat capacity at fixed temperatures is investigated to identify the origin of the field induced first order phase transition in polycrystalline Ce(FeAl…
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…
Resistivity and thermoelectric power measurements on CeFe and its pseudobinaries
M. K. Chattopadhyay, Meghmalhar Manekar, Kanwal Jeet Singh +3
Resistivity and thermoelectric power (TEP) measurements on CeFe and two of its pseudo-binaries Ce(Fe, 5% Ir) and Ce(Fe, 7% Ru) between 78K and 275K are reported. The re…
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…
