Abstract

Using an extensive scaling analysis of the transport properties in twinned YBa2Cu3O7δ crystals we have experimentally found the predicted change in the universality class of the Bose-glass to liquid transition when the magnetic field is applied at small angles away from the direction of the correlated defects. The new dynamical critical exponent is s=1.1±0.3.
