A magnetic tunnel junction Fe3O4/MgO/Fe with (001) layer orientation isconsidered. The junction magnetic energy is analyzed as a function of the anglebetween the layer magnetization vectors under various magnetic fields. Thetunnel magnetoresistance is calculated as a function of the external magneticfield. In contrast with junctions with unidirectional anisotropy, asubstantially lower magnetic field is required for the junction switching.
