Аннотация:
We have observed the finite voltages along the c-direction of the Ag-sheathed Bi-2223 multifilament tapes, which were detected by the voltage leads attached to the opposite broad faces of the tape. Theoretical analysis using a magnetic flux creep and flow model and a simplified electric network model is provided. The non-uniformity of the mass density of the core and the asymmetric distribution of the cores over the transverse cross section result in a finite voltage.
