Abstract

We have systematically applied the intercalation technique to the layered superconducting oxides in order not only to develop a new high-Tc superconducting nanohybrid, but also to investigate the mechanism responsible for high-Tc superconductivity. In the light of the Lewis acid-base concept, we have recently synthesized new types of high-Tc superconducting intercalation compounds: M-X-Bi2Sr2Can-1CunOy (M = Hg,Ag; X = Br,I; n = 1,2). According to X-ray absorption spectroscopic analysis, intercalated HgX2 is stabilized in a molecular form with linear symmetry, which is the first example of molecular HgX2 in a solid matrix, and the intercalated AgI has an α-AgI-like structure with distorted tetrahedral symmetry, which is consistent with the significant rapid ionic conductivity of AgI-intercalate in the temperature domain 25-300°C.
