Es. Reddy et al., Microstructural and magnetic properties of textured GdBa2Cu3Oy/Gd2BaCuO5 composites fabricated from Gd2BaCuO5 preforms, MAT SCI E B, 57(3), 1999, pp. 179-185
Bulk GdBa2Cu3Oy superconductors with uniformly distributed inclusions of mi
cron-sized Gd2BaCuO5 (211) have been prepared by the infiltration and textu
ring of pre-shaped porous 211 preforms with liquid phases, in a high purity
Ar atmosphere. The microstructural features at various stages of processin
g with particular emphasis on the nature of the 211 inclusions are studied.
The superconducting properties like the transition temperatures and critic
al current densities of the resulting composites are discussed. (C) 1999 El
