Abstract
The optimization of high-quality melt-processed ternary (Nd-Eu-Gd)Ba2Cu3O7-δ composite samples has been carried out to achieve the largest pinning. Our results suggest that the interaction between the twin planes and the fine second-phase precipitate forms a strongly pinned entangled vortex liquid in which vortices are correlated along the c axis. This pinned vortex liquid freezes into a glassy state at low temperature rendering high critical current density, Jc. The maximum Jc can be achieved in as-grown optimally annealed twinned sample with second phase precipitate without disturbing the twin influence.
