Abstract

Within the local-spin-density functional formalism and with the use of unoccupied states potential correction, the electronic structure of CaCuO2 and Sr2CuO2Cl2 has been calculated self-consistently by use of the LMTO-ASA method. Both compounds were found to have an insulator-type ground state, with gap values of 1.1 and 2.0 eV and magnetic moments per copper atom equal to 0.54 and 0.67 μB for CaCuO2 and Sr2CuO2Cl2, respectively. A comparison was made with the calculated results for the antiferromagnetic semiconductor La2CuO4.
