Interplay of YBCO and Embedded 211 Particles in Melt-Textured YBCO Superconductors

摘要

Local orientations of superconducting YBa{sub}2Cu{sub}3O{sub}x (123) and embedded Y{sub}2BaCuO{sub}5 (211) particles within bulk, melt-textured 12.3 samples are studied on a local scale by means of electron backscatter diffraction (EBSD). The embedded Y{sub}2BaCuO{sub}5 (211) particles do not show any preferred texture, but their presence within the 123-matrix alters the growth of the 123-phase, independent of the orientation. EBSD enables to analyse the interactions between the 123- and 211-phases in detail.
