Abstract

The temperature dependence of resistivity of Bi₂(Sr, Ca, Y)₃Cu₂O_y 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 Bi₂Sr₂Ca_1-xY_xCu₂O_y and Bi₂Sr_1.5Ca_1.5-xY_xCu₂O_y. 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.
