TiusanMonocrystalline Fe(100)/MgO(100)/Fe(100) magnetic tunnel junctions (MTJ), elaborated by Molecular Beam Epitaxy constitute ideal systems for validation of specific concepts related to the spin polarized transport in crystalline multilayers. The analysis of the band structure shows that the Fe(100) behaves as a half-metal with respect to the D1 electronic symmetry; this new concept of spin polarization/filtering in terms of symmetry being at the origin of huge magnetoresistive effects theoretically predicted in these systems. Our magnetotransport results validate the effects of electronic symmetry filtering. Moreover, they illustrate the influence of the electroni...
