Samples of polycrystalline YBa2Cu30 v superconductor were prepared by melt textured growth (MTG). The melting parameters, including temperature gradient at solidification, melting temperature, melting time and cooling solidification rate, are key factors in preparing textured samples.

YBa2Cu307 crystals fabricated by a quench and melt growth process contain fine Y2BaCuO5 particles. These fine precipitates are considered to have three beneficial effects: they suppress crack formation; they promote oxygen diffusion; and they act as pinning centres. Such crystals exhibit larger flux
In this article the results of a systematic investigation of the electromagnetic properties of sintered YBaCuO superconductors are presented. Many technological applications of type II superconductivity rely on the control and optimization of flux-line pinning mechanisms. Thus, the aim of this work
