✦ Synopsis

The distribution, creep and pinning of intergranular vortices were studied at 77 Kin Y1Ba2Cu30]-o in which the intergranular space was partly filled with silver. The reduction of the diamagnetic shielding, the trapped field as well as the activation energy for intergrain flux creep from 1.6 eV down to 0.3 eV were observed. This energy does not depend on grain decoupling and the number of pinning centers.

We studied the distributions of the diamagnetic shielding, the Meissner effect and the trapped field across ring-and disc-shaped samples of Y IBa2Cu307 at 17K, and their dependence on the applied magnetic field (0-1200G) and time. Geometry-dependent modifications were observed for the shielding and
