Abstract
The effect of chemical composition variations on the flux pinning and physical properties of (Y,Nd)1+xBa2-xCu3O7-d superconductors was studied in powders processed by solid-state reaction and equilibrated in air at 910 C. An extended region of single-phase crystal structures was determined for compounds with Ba = 2.0 to 1.7 and Nd = 0 to 1.3. At 77 K, the composition (Y0.6Nd0.4)Ba2Cu3O7-d had the highest Jc and flux pinning properties above 2 T, and showed over a magnitude of improvement for applied fields > 3 T compared to YBa2Cu3O7-d. At 65 K, the YBa2Cu3O7-d composition had the highest Jc(H) properties. With decreasing Ba content (Citation
