Time relaxation of magnetization in type-II superconductors
G Ravikumar P Chaddah K V Bhagwat
We assume that currents induced by isothermal changes of magnetic field decay logarithmically with time. Incorporating this time dependence into the critical state model, we obtain logarithmic relaxation rate of magnetization as a function of field for the case of an infinite cylinder. We compare these calculations with our earlier calculations on infinite slab geometry.

Volume 22 Issue 3 May 1999 pp 275-278 High Tc Superconductors: Thin Films And Vortex Pinning
We present DC magnetization data indicating a first-order phase transition in the vortex state of CeRu2, with the higher entropy phase exhibiting enhanced pinning. Minor hysteresis loops show evidence of supercooling of the higher entropy phase as the phase boundary is crossed both isothermally as well as at constant field. These features are shown to be absent across the Bragg-glass to vortex-glass transition in Bi2Sr2CaCu2O8. The supercooling is more persistent in the constant field case.
