Abstract

Three quaternary sulfides ACuFeS₂ (A = K, Rb, Cs) with the ThCr₂Si₂-type structure were prepared from alkali metal carbonate A₂CO₃, Fe₂O₃, and CuO by CS₂/N₂ sulfurization. All of the samples show semiconducting behavior. Magnetic susceptibility data indicate the presence of localized moment arising from the di- and trivalent iron ions. The semiconducting properties observed in this system are in contrast to the metallic behavior predicted by theoretical calculations.
