Description
The electrical resistance of carefully prepared sintered pellets of YBa2Cu3O7-δ has been measured in the temperature range from 65 to 150 K at magnetic fields up to 12.5 T. The dependences of the sample resistance on the magnetic field for several fixed temperatures below Tc are shown. At T = 65.5 K the sample resistance remains zero even up to a magnetic field of B = 12.4 T. Plots of the upper critical field (Bc2) as a function of temperature near Tc are presented. They give evaluated values of Bc2 = 120 T at T = 0 K and of Ginzburg-Landau coherence length ξGL = 1.4 nm at T = 0 K which are typical for this class of materials
