摘要：
On the Fe-Al alloy near the Fe3Al stoichiometry the magnetoresistance and hysteresis loops were measured in the ordered and disordered states. Atomic order and structure were checked by Mossbauer spectroscopy and TEM. The disordered sample shows a usual behaviour of bulk ferromagnetics. The ordered one exhibits large decrease of resistivity in the magnetic field and lower ability to reach the saturation. The large magnetoresistance effect is explained on the basis of similarity between naturally layered Fe3Al structure and artificial multilayers taking into account probable perturbation of spin orientation on the sublattices occupied by the iron atoms with lower magnetic moments.
