The structure of epitaxially sputtered single-crystalline
multilayers
was studied using X-ray diffraction.
As the thickness of the Fe layers is increased
the structure of the Fe layers changes from vertically expanded
fcc (001) to relaxed fcc (001), and finally, to bcc (011), thus
identically replicating the structural behavior found in thin Fe
films on Cu(001) single crystals. Corresponding to the
structural transitions of the Fe layers are changes in
the magnetic properties. The relaxed fcc phase contains
non-magnetic Fe, which can lead to antiferromagnetic coupling of
the 
layers across the Fe layers.
