✦ Synopsis

Trapped flux, persistent current, diamagnetic shielding and Meissner effect in a ring and a disk of YIBa2Cu307 have been studied by the measurement of the distribution of magnetic field across the sample at 77K in applied magnetic field up to 1000 G. It was observed that penetration of magnetic flux into a disk depends on applied field only. The penetration of flux into the ring depends on both applied magnetic field and time. The dependence of the decay rate of trapped field on an initial trapped field revealed the vortex-persistent current interaction in the ring. The vortex motion in the ring is the combination of flux-creep and flux-flow processes.
