Type of article: Article

Summary

THE DYNAMIC CONDUCTIVITY AND PERMITTIVITY SPECTRA OF A SUPERCONDUCTING YBCO FILM ARE MEASURED DIRECTLY AT FREQUENCIES 8-32/CM WHICH ARE SMALLER THAN THE ENERGY OF THE SUPERCONDUCTING GAP. IN THE NORMAL PHASE PERMITTIVITY AND CONDUCTIVITY REVEAL A METALLIC BEHAVIOUR WITH A CHARACTERISTIC PLASMA FREQUENCY ABOUT 3,200/CM AND DAMPING ABOUT 380/CM. IN THE SUPERCONDUCTING PHASE THE VARIATION OF PERMITTIVITY IS IN ACCORDANCE WITH THE CLASSICAL CONCEPTS REGARDING THE LOW-FREQUENCY ELECTRODYNAMICS OF SUPERCONDUCTORS. THE POLYCRYSTALLINE STRUCTURE OF THE FILM SUBSTANTIALLY DISTORTS THE BEHAVIOUR OF THE DYNAMIC CONDUCTIVITY IN THE SUPERCONDUCTING PHASE.
