Abstract:
1223 Hg-based Hg-Ba-Ca-Cu-(O,F) superconductor was prepared. It was proved that F entered 1223 superconductive phase and located at O(3) lattice site. The critical temperature T c of the samples doped with fluoride but without annealling is as high as 133.8 K, which is ~22 K higher than that of Hg Ba Ca Cu O standard samples. With the substitution of F with O, the carrier′s concentration in the superconductor is nearly close to the optimum value, which leads T c of F-doped samples increasing greatly.
Key words: 1223 Hg-based supercondutor, Quasi-perovskite structure, Superconductivity, Doping-fluoride
