ABSTRACT:
Fine diameter continuous multifilament superconductor yarns comprising niobium carbonitride may be prepared. The fibers of which the yarn is composed possess a very high transition temperature (T.sub.c of 17.degree.K) combined with a good upper critical field (H.sub.c2 of 125 kG) and critical current density (J.sub.c of 10.sup.5 amps/cm.sup.2 at 40 kG). This invention provides excellent superconductor materials in the form of continuous fine diameter multifilament yarn.
