| Abstract: | The exchange constants observed in the rare earth iron garnets, obtained from fitting magnetization and paramagnetic susceptibility
as a function of temperature have been analysed in terms of Anderson’s theory of superexchange. The transfer integrals and
covalency parameters have been obtained for various rare earth ions overlapping with oxygen. |
