【Abstract】 The substitution effect of Sn4+ and/or Ca2+ on superconductivity in YBa2Cu3Oy ceramics was studied. It is found that the influence of the two kinds of dopants on superconductivity is different; and the donor-acceptor compensation effect occured when both of Sn4+ and Ca2+ elements were introduced into the material together. A preliminary discussion has been given in the present paper.更多还原
