Texture analysis and microstructural features in YBa2Cu3O6+x zone-partial-melted samples with Y2BaCuO5 additions

Rod-shaped samples of YBa2Cu3Osigma+x (Y123) with different contents of Y2B aCuO5 (Y211) are textured by the partial-zone melting method in order to pr oduce single-domain specimens. The microstructure and magnetic properties o f the samples are analyzed as a function of the Y211 initial addition. Y211 precipitates are more homogeneously distributed and smaller, and the super conducting properties of the sample also improve, so when the initial conte nt of Y211 increases, J(c) values are high. Texture analysis is carried out by the x-ray pole figure technique.
