Summary

THE CRITICAL TEMPERATURE AND THE ELECTROMAGNETIC PROPERTIES OF NIOBIUM-TITANIUM/COPPER COMPOSITES WITH VERY FINE SUPERCONDUCTING FILAMENTS, PREPARED BY THE MULTIPLE COMPACTION PROCESS, WERE MEASURED. THE CORRESPONDING CRITICAL CURRENT DENSITY, VOLUME PINNING FORCE, EFFECTIVE TRANSVERSE RESISTIVITY, HYSTERESIS AND EDDY CURRENT LOSSES AT DIFFERENT FIELD AMPLITUDES AND FREQUENCIES UP TO 50 HERTZ, WERE DETERMINED. THE UNEXPECTED VERY HIGH CRITICAL CURRENT DENSITIES AT LOW FIELDS AND THE MAXIMUM VOLUME PINNING FORCE OBTAINED AT UNUSUALLY LOW FIELDS WERE EXPLAINED THEORETICALLY BY THE EXISTENCE OF A ONE-DIMENSIONAL FLUX LINE LATTICE IN THE FILAMENTS.
