Abstract

Melt processing of SmBa2Cu3Oy (Sm-123) is done in argon atmosphere by the solid liquid melt growth (SLMG) route, with increasing concentration of insulating Sm2BaCuO5 (Sm-211) content. The effects of Sm-211 on the microstructure and on the behaviour of current density (Jc) in high magnetic fields, are discussed. It is observed that as the Sm-211 concentration is increased, the morphology of the trapped 211s change from acicular having a high aspect ratio to nearly spherical. The Jc increases for low additions of 211, but for high concentrations, the Jc drops drastically. The above data is explained on the basis of pinning from the 211 particles and the matrix.
