【Abstract】 In this study, by partly replacing BaCO₃ and Y₂O₃ with BaF₂, BaCl₂ and YF₃ respectively,a series of samples were synthesized. The R-T, M-T curves and X-ray diffraction patterns of the samples were measured. From experiments, it was found that a small amount of dopant has little effect on T_ce, but makes the M-H curves changed. When the amount of dopant is increased, the superconductivity of samples disappeared. The effect of doping with Chloride on the superconductivity of Y-Ba-Cu-O is reported.更多还原
