A covalent magnetic exchange interaction formula for describing the transition-metal ion pairs in strong covalent complex molecules has been derived in terms of the Girerd-Journaux-Kahn's magnetic theory and the Cuire-Barth-Canny's covalent theory. By this formula the relationship between the magnetic exchange coupling parameter J and the covalent parameter<space>N has been studied. It is shown...
As a development of our recent works about homodinuclear clusters, a theoretical formula for describing the exchange interaction of heterodinuclear system has been derived in terms of the natural magnetic orbital method. By means of this formula and the Double-Slater-Function (DSF) calculation procedure, the various integrals in the magnetic expression have been calculated. The theoretical curve of...
