ABSTRACT
Compared with mono-rare earth 123 films, ternary rare earth (Nd,Eu,Gd)Ba[sub 2]Cu[sub 3]O[sub 7-δ] (NEG123) films show higher critical current density (J[sub c]) and improved irreversibility field (H[sub irr]), but no increase in the characteristic field corresponding to a crossover from a low-field plateau to a linear region in a log J[sub c]–log H plot. At intermediate fields, J[sub c] vs H scales as H[sup (-0.5±0.05)] for NEG123, in contrast to H[sup (-0.73±0.05)] for mono-rare earth samples such as Gd123. The slow power decay of J[sub c] vs H together with the improved J[sub c] and H[sub irr] strongly implies that extra flux pinning centers exist in NEG123, which are thought to be noncorrelated stress fields induced by lattice mismatch. © 2004 American Institute of Physics.
