Description
The resistance of single-phase samples of YBa2Cu3O/sub 7-//sub δ/ has been measured as a function of temperature in magnetic fields up to 23 T. The nearly linear temperature dependence of the resistivity characteristic of this high-T/sub c/ material was observed from room temperature down to about 120 K. Between 120 K and T/sub c/0∼92.5 K the resistivity drops more quickly. Analysis shows this behavior to be consistent with the effect of three-dimensional superconducting fluctuations as was shown by Tsuei et al. for zero magnetic field. A critical-field slope of 3.2 T/K is obtained
