Mezentseva, V. Gasumyants, O. Martynova, O. Aleksandrova, D. Potapov, A. Lapshin] Two series of yttrium cuprates Y0.8Ca0.2Ba2Cu3 − y ZnyO7 − δ (0 ≤ y ≤ 0.25) with isovalent substitutions and Y1 − x CaxBa2Cu2.8Zn0.2O7 − δ (0 ≤ x ≤ 0.25) with heterovalent substitutions are investigated. It is demonstrated that these compounds have an YBa2Cu3O7 − δ-type structure in the orthorhombic crystal system. The isomorphous miscibility ranges and the concentration dependences of the unit cell parameters are determined for the solid solutions based on yttrium cuprates. The temperature dependences of the resistivity and the dependences of the critical temperature on the dopant concentration are analyzed. Pleiades Publishing, Inc., 2006 Mezentseva L.
