Summary

THE MAGNETIC FIELD DEPENDENCE OF THE TIME CONSTANT OF COUPLING CURRENTS AMONG FILAMENTS IN A MULTIFILAMENTARY SUPERCONDUCTING NIOBIUM-TITANIUM WIRE WAS STUDIED. THE TIME CONSTANT WAS MEASURED WITH RESOLUTION OF 0.1 T IN THE BACKGROUND FIELDS FROM ZERO TO 10 T BY A NEWLY DEVELOPED DIRECT METHOD. THE MEASURED TIME CONSTANT VALUES SHOWED A PEAK OF AROUND 1 T WITH A MAXIMUM TIME CONSTANT OF 43 MS. THIS PEAK EFFECT COULD BE THEORETICALLY EXPLAINED BY THE EFFECTIVE TRANSVERSE RESISTIVITY AND EFFECTIVE PERMEABILITY OF THE COMPOSITE WIRE WITH THE MAGNETIC FIELD DEPENDENCE.
