Resumen:
We used a micromechanical torsional oscillator to measure the magnetic response of a twinned YBa2Cu3O7-delta single crystalline disk near the Bose glass transition. We observe a clear anomaly in the temperature dependence of the magnetization consistent with the appearance of a magnetic shielding perpendicular to the correlated pinning of to the twin boundaries. This effect is related to the thermodynamic transition from the vortex liquid phase to a Bose glass state.
