Superconductivity with High-Frequency Currents

Abstract

FURTHER experiments have been carried out by us in this laboratory on the phenomena of superconductivity with alternating currents of high frequency, following those already reported.¹ In these experiments, observations have been made on the resistance of a conductor at low temperatures when both alternating (frequency 12 × 10⁶) and direct currents were flowing simultaneously. The curves show the variation of the resistance with the temperature; the temperature was controlled and estimated by the vapour pressure of liquid helium.
