Sažetak
Comparative studies on Bi-2212 single crystal, Bi-2212 tape and 2223 tape have been carried out using ac susceptibility, magnetization and magnetoresistivity measurements. It was found that the pinning strength increases with sequence of 2212 single crystal, 2212 tape and 2223 tape. This is consistent with results of the pinning potential, U-0, determined by using resistance measurements in magnetic fields. The differences in flux pinning are attributable to the different processing conditions which result in the difference in dislocation density.
