摘要：

The effect of Y substitution for Ca on superconducting properties has been investigated in Bi2Sr2CaCu2O8+d films prepared by liquid phase epitaxial method. The Y concentration in the film, x(S), increased in proportion to that in the solution, x(L), in the region of 0 less-than-or-equal-to x(L) less-than-or-equal-to 0.2, and then it was saturated. The incorporation ratio of Y in solid and in liquid, x(S)/x(L), for 0 less-than-or-equal-to x(L) less-than-or-equal-to 0.2 was found to be about 3. The x(S) dependences of the zero-resistance temperature and the carrier-concentration showed that about half of the Y concentration incorporated in the films contributes to the effect of the Y substitution obtained in sintered materials.
