Stoichiometric YBa2Cu3O7−δ (Y123) samples doped with excess Nd2O3 and La2O3 additions were melt processed in air. Because decomposition and reformation of 123 occurs during melt processing, lighter rare-earth ion substitution in 123 takes place. As the lighter rare-earth ion sizes (Nd, La) are comparable to that of Ba2+, in addition to Y ion site substitution, partial substitution into the Ba2+ sites is also anticipated. The Tc and magnetic properties of lighter rare-earth oxide doped samples were analyzed and compared with undoped Y123 to investigate the flux pinning enhancement due to these substitutions. The lighter rare-earth oxide doped, melt processed 123 shows significant improvement in magnetization compared to undoped samples, which is likely due to point defects created by partial substitutions of the lighter rare-earth ions. © 1995 American Institute of Physics.
