N2 - Single crystals of La2-xCa1+xCu2O6-x/2+δ have been grown by the CuO flux method. After annealing under a high partial pressure of O2, these crystals showed zero resistance at 41 K and a perfect shielding effect (3% Meissner signal). These crystals also showed metallic behaviour parallel (a,b) and perpendicular (c) to the basal plane, with an anisotropy of about 30 at room temperature. The Ginzburg-Landau coherence lengths were estimated from Hc2 measurements: ξab=33 A ̊ and ξc=12 A ̊. The anisotropy factor of 3 is fairly small for a high-Tc superconductor.
