摘要:
Recently, we have successfully synthesized new type of high-Tcsuperconductors of (HgX2)0.5Bi2Sr2Cam-1CumOy(X˭Br, I, and m = 1, 2) by means of intercalation technique. From the X-ray diffraction(XRD) and X-ray absorption spectroscopy(XAS) analyses, we found that the intercalated mercuric halides are stabilized as the isolated gaseous molecules in the interlayer space of superconducting lattice, leading to an increase of basal spacing. A small amount of charge transfer between guest molecule and host lattice could be observed upon intercalation with a slight depression ofTc. For the extension of metal halide intercalation into high-Tc, superconductor, we have developed new type of hybridized superconducting nanohybrid with periodic stacking of organic and superconducting layer by stepwise synthetic approach, where organic compounds are stabilized in the form of organic-inorganic complex salt in-between Bi-O double layers of Bi-based high-Tccuprates. The synthetic strategy proposed here can be applicable to many other layered systems
