The magnetic profile of Fe/Cr_N/Fe bcc(001) films has been calculated by means of first principles density functional theory. It is shown that the magnetic profile of the chromium spacer can be expressed in terms of spin density waves (SDW). The dispersion and amplitude of the SDW are determined and the effects from the finite film thickness are observed and discussed. It is found that the SDW wave vectors are quantized and that for certain Cr thicknesses two SDWs with different wavelengths coexist. Connections to the magnetic interlayer coupling are discussed. ©1999 The American Physical Society
