Fluctuation Effects on the Magnetic Properties of Superconducting Layered Compounds
Superconducting layered compounds intercalated with organic molecules have attracted considerable attention recently because of their unique structural and electronic properties which may make them intrinsically two-dimensional superconductors. Evidence for two-dimensional behavior, or at least very strong two-dimensional correlations, has been observed in the thermal1 and magnetic2 properties of these materials. In this paper we report the results of a preliminary investigation of the low-field magnetic behavior of the intercalated superconductor TaS2(pyridine)1/2, undertaken to examine further the possibility of two-dimensional superconductivity in these systems. Particular emphasis has been placed on studying the enhanced diagmagnetism due to thermally induced superconducting fluctuations above the superconducting transition, since such fluctuation effects are known to be sensitive to the dimensionality of the system.
