Abstract Copper(II) oxide containing different amounts of sodium has been prepared. Thermo-analytical studies reveal differences in behaviour between sodium-incorporated samples and the control sample. A strong esr signal withg=2.1 is explained by assuming a square planar configuration around the Cu2+ ion. The spin concentration is found to vary linearly with the sodium content, each sodium decoupling the spins of 40 Cu2+ ions in CuO. The signal is found to be present even in a reduced sample. The origin of such species is explained on the basis of antiferromagnetic decoupling of spins.
