Preparation and characterization of magnetically textured Y and DY 123 compounds

The authors prepared homogeneously (i.e through volume-textured material in comparison to sinter-forged samples where the texture is preferentially at the surface) c-axis-textured samples with approximately 200 mu Omega -cm resistivity at 100 K and approximately 88% density by aligning powders in a magnetic field and then sintering. Light microscopy, X-ray diffraction, and transport J/sub c/ measurements were used to characterize the samples. Longer sintering times improved the texture. Dilute suspensions in which particles did not touch could be very well aligned. Such samples, encased in epoxy, had 50% of
