Abstract

Textured YBa₂Cu₃O_7-x (YBCO) thick films were fabricated in the green state by casting particulate-based suspensions in an applied magnetic field (7 T) at ambient temperature. These films, along with non-aligned films, were fired to various temperatures above the peritectic temperature (≈1020°C) to evaluate the effects of partial melt processing on their microstructural development and performance properties. The degree of domain alignment in the fired films was measured by x-ray diffraction (XRD) analysis. This showed that the aligned films had a high degree of c-axis texture. Examination by SEM/EDAX revealed distinct differences in both the film density and texture development between aligned and nonaligned films. Finally, the magnetic properties of each film were measured at 5 K using a SQUID magnetometer (5.5 T maximum field). These measurements indicated that a high degree of anisotropy was present only in the partial melt processed aligned YBCO films.
