Summary

THE LONGITUDINAL RESISTANCE OF A COPPER MATRIX IN COMMERCIAL MULTIFILAMENTARY SUPERCONDUCTING WIRES WITH VARIOUS NUMBERS AND DIAMETERS OF NIOBIUM-TITANIUM FILAMENTS HAS BEEN MEASURED. IF A CURRENT IS PASSED THROUGH A MULTIFILAMENTARY SUPERCONDUCTING WIRE PERPENDICULAR TO THE SUPERCONDUCTING FILAMENTS, A STATE SPECIFIC TO TWO-DIMENSIONAL SUPERCONDUCTORS IS CREATED. THE TEMPERATURE DEPENDENCE OF THE TRANSVERSE RESISTANCE OF THE SAMPLES USED WAS ANALOGOUS TO THAT OF THE RESISTANCE OF A TWO-DIMENSIONAL SYSTEM. THUS, AFTER THE SUPERCONDUCTING TRANSITION OF THE NIOBIUM-TITANIUM 50 FILAMENTS, A DECREASE IN THE TEMPERATURE LEADS TO A MONOTONIC DECREASE OF THE RESISTANCE DUE TO THE PROXIMITY EFFECT.
