| dc.description | The resistivity has been measured as a function of temperature in magnetic fields up to 12 T for a typical Tl<sub>2</sub>Ca<sub>2</sub>Ba<sub>2</sub>Cu<sub>3</sub>O<sub>x</sub> sample. The resistive transition width has been observed to broaden with increasing field while the transition onset remains unchanged. This broadening can be explained by the flux-creep model. The flux-creep activation energy at the applied field values has been estimated from the slopes of Arrhenius plots of log rho against 1/T. The flux-creep activation energy has been found to be weakly field-dependent (H<sup>1</sup>2/) in high-field regions (>2 T). The upper critical field of the Tl-based superconductor has also been estimated to be 133 T. |
