The peak effect in weakly pinned superconductors is accompanied by metastable vortex states. Each metastable vortex configuration is characterized by a different critical current density J c , which mainly depends on the past thermomagnetic history of the superconductor. A recent model [G. 1 history dependent J c postulates a stable state of vortex lattice with a critical current density J st c , determined uniquely by the field and temperature. In this paper, we present evidence for the… CONTINUE READING
