  3. Abstract:
  4. We have studied the thermally activated flux creep in the newly fabricated superconductors Y3Ba5Cu8O18+δ and Gd3Ba5Cu8O18+δ with transition temperature above 100 K. The thermally activated flux creep model explains the electron share in the magnetoresistivity of the samples in the vicinity of transition temperature T c . The activation energy U in a magnetic field below 15 kOe has been calculated by the corrected thermally activated flux creep model; and the pinning energy is exponentially related to the magnetic field
