Evidence of Two-Dimensional Superconductivity in the Single Crystalline Nanohybrid of Organic-Bismuth Cuprate

Abstract

A coordination compound of HgI(2)(pyridine)(2) can be successfully intercalated into a single crystalline Bi(2)Sr(2)CaCu(2)O(y) high-T(c) superconductor through an interlayer complexation reaction between pyridine molecules and bismuth cuprate pre-intercalated with mercuric iodide. X-ray diffraction and X-ray absorption spectroscopic results clearly demonstrate that the single crystalline nature of the pristine bismuth cuprate remains unchanged even after the intercalation of organic complex as well as those of iodine and mercuric iodide. According to the angle-dependent dc magnetization measurements, the intercalation of bulky organic molecules completely blocks superconductive currents along the c-axis, whereas a superconducting transition along the in-plane direction still occurs in the organic intercalate. In the case of the iodine or mercuric iodide intercalates with smaller lattice expansions, an out-of-plane diamagnetic transition is not wholly quenched but significantly depressed by the intercalation, confirming the reduction of interlayer interaction. The present finding can provide straightforward evidence of the two-dimensionality of high temperature superconductivity in the present cuprate-based nanohybrid material.

“…A high-T c superconductor with 2-dimensional structure, bismuth cuprate, was utilized to investigate the superconducting properties, by intercalating various molecules in its interlayers. [1][2][3][4][5][6] Semiconducting layered materials such as layered TiO 2 or MoS 2 have been reported as new host lattices for hybrid photocatalysis with high specific surface areas. 7,8 Acid-treated clays have been used in the hydrocracking process in the petrochemical industry, 9 layered double hydroxides with HTlc (hydrotalcite-like compound) structures have been reported as hydrogenation catalysts and supports for Ziegler-Natta or bromination catalysis.…”
