چکیده انگلیسی
The effect of Co2+, 3+ and Ca2+ substitution in Y3+ site in YBa2Cu3O7âδ superconductor has been studied. The series of high temperature superconducting samples of Y1âyâxCoyCaxBa2Cu3O7âδ with 0â¯â¤â¯xâ¯â¤â¯0.015 and yâ¯=â¯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, Ï'(T), show that in reserving cobalt fixed sample with the optimum Tc, by substitution of divalent Ca2+ at the trivalent Y3+ site no sensitive increasing happen in the superconducting transition temperature.
