Abstract

Superconducting fiber bundle which contains a multiplicity of carrier fibers such as, for instance, carbon fibers, boron fibers, steel fibers coated with a superconducting layer of a niobium compound of the general formula NbC.sub.x N.sub.y O.sub.z (x+y+z less than or equal to 1), characterized by the feature that the superconducting layer consists of fine-grained B1-structure niobium compound, the mean grain size of which is between 3 and 50 nm.
