摘要

Magnetic and electronic nature have been investigated for the novel layered oxysulfide Sr2CuCoO2S2 (space group 1/4mmm). Sr2Cu2CoO2S2 is the antiferromagnet with T-N (= 200 K) determined by the measurements of neutron powder diffraction and magnetic susceptibility ((Z)). The (Z) shows a broad maximum indicative of two-dimensional antiferromagnetic nature. which is not originated from the (Cu-S)(2) layers but the strongly correlated Co2-O2 squareplanes revealed by the X-ray photoemission spectroscopy.
