The transport properties of sharp antiferromagnetic boundaries between Gd and Fe have been studied. The measurements were carried out with the current perpendicular to the plane at 20 K and up to 8 T in multilayer Gd/Fe of different thicknesses. We have extended the Valet and Fert model for giant magnetoresistive multilayers to explain the results in terms of spin-dependent scattering at the interface that changes its magnitude when the external field decreases the angle of the interface.
