Abstract

The new biaxial alignment technique based on a combination of magnetic field and mechanical force alignment (acting normal to each other) has been applied for the first time to an RE-123 superconductor ceramic, where RE - Eu .92 Yb .08. Biaxial (and hence triaxial) alignment was achieved, at least in the surface layer, as demonstrated by XRD and observation of the twin boundary pattern.
