|Abstract: ||We have measured the magnetoresistivity of polycrystalline Bi2Sr2Ca1-xYxCu2O8+delta (BSCCO) with x = 0, 0.05 and 0.20 and YBa2Cu3O7 (YBCO) in magnetic fields of 4 T. We find Inui et al's model to describe the data in a wide temperature range within the flux creep and flux flow regions. The pinning behaviour in BSCCO due to Y doping is found to be similar to the one with application of magnetic field, with the pinning potentials U-0 around 2000 K. U-0 further decreases to around 1300 K for x = 0.20 in the field of 4 T. The pinnings in YBCO system are found to be stronger compared to BSCCO.|
