摘要：

The effect of Co-2+,Co- (3+) and Ca2+ substitution in Y3+ site in YBa2Cu3O7-delta superconductor has been studied. The series of high temperature superconducting samples of Y1-y-xCoyCaxBa2Cu3O7-delta with 0 <= x <= 0.015 and y = 0.020 were prepared by solid-state reaction method. The samples were characterized for phase purity and lattice parameter variations by X-ray diffraction. The AC susceptibility curves, chi'(T), show that in reserving cobalt fixed sample with the optimum T-c, by substitution of divalent Ca2+ at the trivalent Y3+ site no sensitive increasing happen in the superconducting transition temperature.
