    • Abstract

       

      The exchange constants obtained using the three sublattice model for ferrites and garnets have been analysed using Anderson’s theory of superexchange. The transfer integrals for the 180° and 90° interactions obtained from the experimental values of exchange constants give approximate values of the covalency parameters which are consistent with the chemical theory of covalency.
