Abstract

Physical Sciences Physics Physics, Applied Physics, Condensed Matter Science & Technology
The disordered vortex phases induced by line and point pinning in YBa2Cu3O7-delta are explored. At high defect densities, only a single disordered solid separated from the liquid phase by a melting line is observed. At low defect densities the topology of the phase diagram changes dramatically, with a vortex lattice phase adjoining disordered phases at high or low field. Critical points at the termination of the first-order melting line separate the lattice and the disordered phases. The line defect disordered phases follow the expected Bose glass behavior, while the point defect disordered phases do not exhibit the expected vortex glass behavior.
