(Received 23 September 1998)

The magnetic behavior of thin layers of Cr in Fe/Cr/Fe(001) trilayers and superlattices is studied using the first principles self-consistent RS-LMTO-ASA (real space – linear muffin-tin orbital – atomic sphere approximation) method. The effects of lattice compression and interface mixing are investigated, and it is shown that they can cause large reductions of the Cr magnetic moments. ©1999 The American Physical Society
