Abstract
Magnetic characteristics observed in BiSrCaCuO superconductor were studied. In the
measurement of differential conductance, it was cleared that the mechanism of magnetic memory
effect couldn't be explained by using conventional flux flow model. By changing the density of
external magnetic flux, changes in inductance of a coil in which a superconducting bar inserted
were also measured. The results showed that the filament model was valid to explain the
mechanism of the occurrence of a voltage in superconducting sample. It was concluded that the
electromagnetic characteristics arose from the interaction between the trapped magnetic flux and
weak link of the filament formed in the superconducting bulk.
