Abstract

The variations with x of Tc, thermoelectric power and magnetic susceptibility have been investigated for iodine-intercalated Bi2Sr2CaCu2O8+δIx with 0≦x≦1, using sintered samples of Bi2Sr2CaCu2O8+δ with three different values of δ for the host samples. It has been concluded that the strange x dependence of Tc is due to the x dependence of the hole concentration p in the CuO2 sheets, owing to charge transfer from iodine to the CuO2 sheets, and that the value of p has an upper limit. The effects of halogen intercalation on Tc for the Bi-2223 and 2222 phases are also described.
