We report the synthesis and magnetic properties of the AgI-intercalated misfit-layer cobalt oxide Bi1.8Ca2Co2Oz. The AgI-intercalated Bi1.8Ca2Co2Oz was prepared by the guest exchange reaction from the I2-intercalated one. SEM-EDX analysis exhibited the stoichiometric ratio of Ag/I and the guest concentration as (AgI)Bi1.8Ca2Co2Oz on the basis of Co = 2. After the AgI intercalation, the lattice parameter along the c-axis calculated from X-ray diffraction patterns was 21.68 Å, which was drastically increased not only from the non intercalated host phase (14.68 Å) but also from the I2-intercalated phase (18.08 Å). After the AgI intercalation, magnetic susceptibility measurements revealed that the antiferromagnetic Weiss temperature and the effective magnetic moment in Co ion simultaneously decreased compared with the non-intercalated host compound.
