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.eninfo:eu-repo/semantics/closedAccessHigh-T-c SuperconductorsMagnetoresistancePinning EnergyFlux PinningArticle10.1007/s10948-011-1331-1254725729WOS:000305222200002Q4
