We develop a model of superexchange interactions in W-hexagonal ferrites. We analyse all possible interactions and classify the exchange energies from structural considerations. The spin configuration deduced from the model is in agreement with experimental results. Finally, the effect of preferential substitutions on saturation magnetization and Curie temperature is discussed.
