In the present study we have investigated the interlayer coupling in CeH 2/Fe multilayers by neutron reflectometry. For a wide range of interlayer thicknesses we observe an exchange coupling of the iron layers through the nonmagnetic CeH 2 spacer. In addition to a ferro- and antiferromagnetic alignment of the moments the neutron spectra give evidence of a long-periodic magnetic structure which is identified to be an antiferromagnetic fan-like arrangement of the magnetization vectors in adjacent Fe layers.
