Abstract

Magnetization measurements were performed on melt-processed samples prepared by various processing techniques. Fine Y2BaCuO5 precipitates (~100 Å) were observed by transmission electron microscopy in the samples prepared by melt-processed-meltgrowth and solid-liquid-melt-growth techniques. These precipitates were not observed in samples prepared by conventional melt-texturing techniques. Critical current density, Jc, depended on final microstructure; a larger magnetic hysteresis was always associated with the presence of the fine precipitates. However, the flux-pinning strengths of these precipitates decreased at higher temperatures.
