Abstract

The detailed chemical bond parameters of the rare-earth iron garnets were calculated using the chemical bond theory of complex crystals. Results indicated that RE-O bonds are ionic and Fe-O bonds possess higher covalency. The environment factor defined by electron polarizabilities and covalency was employed to predict spectra chemical shift and Mossbauer isomer shift of Fe ions. The hardness of yttrium iron garnet was predicted, which is in agreement with the experimental value.
