Iodine Intercalation On Bi₂Sr₂Cu₂O_y Single Crystal under the Existence of Pd

Abstract

A new compound has been synthesized by iodine intercalation on Bi2212 single crystal under the existence of Pd. Its lattice parameter along c-axis was 18.44Å shorter than that of I₁Bi₂Sr₂CaCu₂Oy (19.09Å). Fluorescence X-ray analysis microscope data showed that only I₂ was intercalated in Bi2212. The temperature dependence of the in-plane nomal resistivity was metallic-like, while the out-of-plane nomal resistivity was almost temperature independent. The transition temperature (onset) of this intercalated new compound was 85 K in both directions. The thermogravimetric curve showed weight loss of 3.9%.
