Abstract
The structure in MBE-grown Fe/Cr/Fe (d(Fe) = 40 Angstrom, 20 Angstrom < d(C r) < 110 Angstrom) has been investigated with ion beam channeling. The temp erature dependence of the interlayer exchange coupling is strongly dependen t on the growth temperature of the layers. For the layers grown at 573 K th e interlayer exchange coupling is suppressed well below room temperature. T his effect is not related to the strain in the Cr layers, which is found to be largely relaxed and only moderately dependent on the growth temperature . (C) 1999 Elsevier Science B.V.
