Fcc-Fe/Cu(M)(001) (M = Au,Ni) artificial superlattices were prepared.
The interatomic distance of fcc-Fe was changed by the epitaxial growth
on Cu(Au) or Cu(ni) alloy layers. The magnetic moment of Fe is increa
sed up to 2.7mu(B) for only 1% increment of interatomic distance. Furt
hermore, non-ferromagnetic state of fcc-Fe was observed at 1.8% decrem
ent.
