摘要：

We have investigated Fe/Cr artificial multilayers to elucidate the origin of a giant magnetoresistance effect (GMR), by neutron scattering measurement in external magnetic fields up to 0.8 Tesla. Intense diffuse scattering appears around the superlattice reflection corresponding to the antiferromagnetic Fe layer stacking. The magnetic diffuse scattering intensity decreases drastically in magnetic fields, which strongly suggests that the GMR effect in this system is dominated by the appearance of magnetic disorder at the interface between the Fe and the Cr layers.
