The mean field theory proposed originally by Kubo and Ohata for manganites is generalized for a ferrimagnetic galf-metal and applied to the magnetite. The relevance of both the double exchange interaction and the superexcahnge one for the spin ordering in the conducting B sublattice of magnetite is shown.
