Abstract

Magnetic and electronic nature have been investigated for the novel layered oxysulfide Sr₂Cu₂CoO₂S₂ (space group I/4mmm). Sr₂Cu₂CoO₂S₂ is the antiferromagnet with T_N (= 200 K) determined by the measurements of neutron powder diffraction and magnetic susceptibility (χ). The χ 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 square-planes revealed by the X-ray photoemission spectroscopy.
