抄録

The temperature dependence of resistivity of Bi2(Sr, Ca, Y)3Cu2Oy solid solutions has been measured from room temperature to 1073K in both air and N2 atmosphere. The effects of the substitution of Y ions for Ca ions are discussed using the experimental data of electrical resistivity of both Bi2Sr2Ca1-xYxCu2Oy and Bi2Sr1.5Ca1.5-xYxCu2Oy. Therefore it is likely that the Sr/Ca ratio in these solid solutions is related to the effects of the substitution of Y ions for Ca ions.
