Abstract

A new superconducting intercalation compound, AgIBi2Sr2CaCu2Oy, in which the basal spacing is increased by 7.352 Å, has been prepared from the mixture of polycrystalline Bi2Sr2CaCu2Oy and Ag powder under iodine vapor at 190°C in an ambient atmosphere. The X-ray absorption studies on I LI- and Ag K-edges indicate that there is no charge-transfer between the intercalated guest species, AgI and host layer. A slight Tc depression (ΔTc∼13K) upon AgI intercalation is, therefore, probably due to the weakening of interlayer coupling, but the hole donation to the host upon oxygen intercalation may not be excluded.
