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), said superconducting layer formed of fine-grained B1-structure niobium compound, the mean grain size of which is between 3 and 50 nm, and the layer thickness of the superconducting layer is between 100 and 2000 nm, characterized by the feature that the superconducting layer contains occlusions of insulating material uniformly distributed, between the B1-structure niobium compound grains, or that in the superconducting layer, occlusions of insulating material are deposited on all grain boundaries of the B1-structure niobium compound drains, independently of their spatial orientation, or that in the superconducting layer, occlusions or insulating material are deposited at grain boundaries of the B1-structure niobium compound grains with definite spatial orientation within the superconducting layer, or that the superconductive material of niobium compound contains an additional element which increases the conductivity.
