Abstract
Neutron-scattering measurements have revealed that the spin-density wave (SDW) inside the Cr spacer of Fe/Cr magnetic multilayers may be either commensurate (Formula presented) or incommensurate (Formula presented) depending on the temperature and Cr thickness (Formula presented). We theoretically evaluate the magnetic phase diagram of Fe/Cr multilayers under the assumption that the nodes of the SDW lie at the Cr-Fe interface, as found by recent neutron-scattering measurements. While the C phase is never stable under this assumption, the paramagnetic to (Formula presented) transition temperature (Formula presented) takes on a seesaw pattern as the SDW wave vector switches between different allowed values.
