Tb and Ce Doped Y123 Films Processed by Pulsed Laser Deposition

Abstract

To evaluate possible flux pinning enhancement in YBa2Cu3O7(7-x)(Y123) films due to partial rare-earth ion substitutions, Ce and Tb doping are studied. Bulk ceramic targets of varying compositions (Y(1-x)RE(x)Ba2Cu3O7(7-x) were made with several doping levels (x = 0.001 to 0.1, RE = Ce or Tb) by using regular solid-state reaction and sintering procedures. These targets were used to deposit Ce and Tb doped YBCO films onto SrTiO3 single crystal substrates by pulsed laser ablation. Doped YBCO films were characterized for Tc, magnetic field dependence of Jc (at 77 K), microstructure, and other properties. The results are compared to undoped YBCO films processed in similar manner.
