        Magnetic character of magnetite is discussed on the basis of the Wilson model of semiconductors and the Bloch theory of ferromagnetism.  It is concluded that the transformation of magnetite at low temperatures is not caused by the change of axis of easiest magnetization but is primarily connected with the special electronic structure of this crystal.
