We investigated the structure, magnetic and magnetoresistive properties of the antiferromagnetically coupled superlattices [Fe(85Å)/Cr(t,Å)] 12 with the Cr layers thickness t Cr =12.4 and 13.6 Å grown simultaneously on (100)MgO and (211)MgO substrates. It is shown that (211)MgO substrate is appropriate for the growth of (210)Fe/Cr multilayers with a strong uniaxial in-plane anisotropy. The stepwise behavior of magnetization and magnetoresistance is revealed in the case when the magnetic field is applied along the easy axis in the film plane of the (211)
