概要 Systematic investigation was performed experimentally on the effect of the thermal expansion of the samples in the microwave-surface-impedance measurement by the resonant technique, using conventional superconductors, Pb and Nb, with various sample sizes. The measurement of the surface reactance, X-S, was found to be very sensitive to the thermal expansion, whereas that of the surface resistance, R-S, was insensitive. We propose a new relation between the measured experimental data and the surface impedance, to deal with this problem. We also propose a quantity which represents the degree of the thermal expansion in the microwave measurement. (c) 2005 Elsevier B.V. All rights reserved.
