High-Frequency Resistance of Tin and Indium in the Normal and Superconducting State

Abstract

Additional measurements have been made on the surface resistance of tin and indium near 24 000 Mc/sec. The results are in general agreement with those reported previously. The high-frequency resistance appears to be varying with frequency in the superconducting region as the three-halves power rather than the predicted second power. This appears to be the case for both tin and indium.
