Abstract

Effects of intercalation of Br and Li into Bi₂Sr₂Ca_n-1Cu_nO_2n+4 (n = 1, 2, 3) have been investigated. For Bi-intercalated samples of n = 2 and 3, intercalation compounds Bi₂Sr₂Ca_n-1Cu_nO_2n+4Br with enlarged unit cells along the c-axis are synthesized. For Li-intercalated samples, it is not clear whether Li atoms act as intercalants or oxygen getters. For lightly Br- and Li-intercalated samples, the electrical resistivity, the Hall coefficient and T_c change depending on the quantity of intercalants, which is attributable to charge transfer between intercalants and CuO₂ planes. For n = 3, T_c decreases by the intercalation of both Br and Li, suggesting that Bi₂Sr₂Ca₂Cu₃O₁₀ has almost optimum hole concentration to attain the maximum of T_c. In conclusion, the intercalation is effective for controlling the carrier concentration in CuO₂ planes.
