Abstract

The normal state properties of Y_1-xCa_xBa₂Cu₃O_y have been investigated for 0≤x≤1.0. The samples revealed the normal state temperature slope of undoped samples over a wide compositional range. It is discussed that the electrical conduction takes place through conducting channels above the solubility limits and the semiconductivity should appear slightly above the percolation threshold. Intergrain regions repaired by excess Ca were argued to be responsible for the retained normal state temperature dependence of Y_1-xCa_xBa₂Cu₃O_y up to x=0.8.
