Özet
In the present work, Bi-Pb-V-Sr-Ca-Cu-Ti-O bulk samples with nominal composition (BiPb)(2)V (x) Sr2Ca3Cu4-y Ti (y) O12+delta with x=0.1 and y=0.050, 0.10, 0.2, and 0.3 have been prepared by the melt-quenching method. The magnetoresistance of the samples has been measured for different values of the applied magnetic field. The thermally activated flux creep model has been studied in order to calculate the flux pinning energies. The flux pinning energies calculated increase with increasing Ti-content, and decrease with applied magnetic field.
