Fluctuation Effects in the AC Impedance of One-Dimensional Superconductors

Abstract

This paper describes the present status of a continuing study12 of the ac complex impedance Z(T) of filamentary tin whisker crystals in the transition region. Measurements of Z(T) probe the mean-field behavior in the superconductor well below T c , and they provide an extra dimension of information over dc measurements in the fluctuation region. From Z(T) well below T c cne can determine the mean-field transition T c0 within 0.1 m°K and measure directly |Ψ(T)|2 or n s (T). In the fluctuation region information related to the fluctuation-induced |Ψ|2 can be obtained as well as the fluctuation resistance and paraconductivity.
