Abstract
Transport measurements on YBa 2 Cu 3 O y have revealed strong history dependences in pinning properties of the vortex solid. By using an annealing current to control exposure of the vortex system to the disorder potential, we were able to study the development of such hysteretic responses, across the region of the vortex freezing transition. We have explained the observed behaviour in terms of coexistent vortex liquid and solid phases.
