Summary

IT IS SHOWN EXPERIMENTALLY, THAT THE CURRENT-VOLTAGE CHARACTERISTICS OF A TWISTED NIOBIUM-TITANIUM MULTIFILAMENTARY SUPERCONDUCTOR PLACED IN A PERPENDICULAR MAGNETIC FIELD DIFFER FROM THOSE OF UNTWISTED SUPERCONDUCTORS. IL WAS EXPLAINED BY THE CURRENT TRANSFER ACROSS THE NORMAL METAL MATRIX DUE TO THE INHOMOGENEOUS ELECTRIC FIELD DISTRIBUTION ALONG EACH FILAMENT. INHOMOGENEITIES ARISE AS A RESULT OF VARYING THE ANGLE BETWEEN THE EXTERNAL MAGNETIC FIELD AND FILAMENT AXIS. SEVERAL MODEL CONDUCTORS WERE PREPARED TO INVESTIGATE THE ROLE OF THE NORMAL METAL MATRIX RESISTIVITY AND THE GEOMETRICAL ARRANGEMENT OF FILAMENTS.
