Abstract
High T-c bulk superconductors Y(Tm)Ba2Cu3O7-x and YSryBa2-yCu3O7-x wer e pre pared following new synthesis routes by the method of thermal de composition of polynuclear coordination complexes. The best supercondu cting samples were obtained using oxalic and malic acids as ligands. T he effect of substituting of Pa by Sr nas a decrease of T-c with incre asing the Sr:Ba ratio. Electrical resistance, magnetic susceptibility and structural measurements have been performed on the superconducting samples.
