Abstract

Low angle neutron scattering experiments performed on Ag/Ni superlattices show the appearance of a low angle peak attributed to the doubling of the chemical period, as a consequence of the antiferromagnetic coupling of the magnetic moments in adjacent nickel layers. This is confirmed by polarized neutron experiments. The variation of the intensity of this peak with temperature is in accordance with a classical model of antiferomagnetism.
