Description

We have observed the decay of trapped flux in the superconducting compound Y1Ba2Cu3O/sub 6.5+//sub δ/ with T/sub c/ = 90 K at liquid-nitrogen temperature (77 K). Measurements were done on samples in the form of a disk, a ring, and a cut ring. The results showed similar logarithmic decays with time for all samples, in good agreement with Anderson's flux-creep theory. This may indicate that our results were mainly due to microscopic vortex creep and not due to a macroscopic persistent current
