Abstract Eu(Ba(sub 1-x)Nd(sub x))(sub 2)Cu(sub 3)O(sub 7 plus delta) were systematically studied in order to understand how the valence of the rare earth elements, ionic sizes and magnetic moment affect the crystal structure and magnetic and electrical properties. Differential thermal analyses were carried out to check the phase purity, X-ray data were least-squares fitted to determine the lattice parameters, and DC-SQUID magnetometry was used to characterize the superconducting properties. These results showed that the crystallography is consistent with other EuLR123ss series, LR=La,Pr,Eu. The lattice parameters vary with the ionic radii of the rare earth ions.
