摘要：the invention concerns a supraleitendes faserb\ündel,consisting of anumber with a superconducting layer of a niobverbindung the general formula nbcxnyoz(x + y + z little \\/ 1) coated tr\ägerfasern (1), such ascarbon fibre, borfasern,steel.for high values of the critical and critical current intensity necessary to achieve asuperconducting layer (2),the fine-grained b1 structure nioboxycarbonitrid (4) whoseaverage grain size is between 3 and 50 nm.our store of isolierendem material (5) in thesuperconducting layer (2), the formation of pinningzentren supported.the production ofnioboxycarbonitridschicht takes place with the help of chemical deposition from the gasphase by the use of plasmaaktivierung and \\/ or a ultraschallfeldes and, whereappropriate, ait unterdruckes.as an alternative to the chemical production process is aphysical process will be used.in a tr\ägerfaserb\ündel a tr\ägerfaserbandfragmented and not a full coating of the tr\ägerfasern with nioboxycarbonitrid bycathode sputtering power.immediately following the superconducting coating can be a

further coating of the fibers with high-purity copper or aluminium.
