Abstract: We present here the results of our investigations of the structural and superconducting properties of thin films of Lu(1-x)M(x)Ba(2)Cu(3)O(7-delta) (M=Ce, Pr, and Tb), the three ambivalent rare-earth ions. Our results show that Pr and Tb ions are in the trivalent state and Ce ions are tetravalent. Structural (in)stability of the parent material LuBa2Cu3O7-delta forms the basis of our arguments. We suggest a simple model to account for the influence of Pr ions on superconductivity in cuprates.
