Abstract

Analyses of a copper-deficient series of Strontium Copper Oxychloride polycrystalline samples are reported. Magnetic susceptibility, X-ray powder diffraction, and differential thermal analyses show a small Curie-type magnetic signal correlates with =0.6% (excess) copper ions in the nominally stoichiometric material. The analyses also imply that the extra magnetic signal is from an impurity phase, possibly related to Strontium Copper Oxide. The concentration of the impurity phase can be controlled by varying the copper stoichiometry.
