Abstract

Fcc-Fe/Cu(M)(001) (M = Au,Ni) artificial superlattices were prepared. The interatomic distance of fcc-Fe was changed by the epitaxial growth of Cu(Au) or Cu(Ni) alloy layers. The magnetic moment of Fe is increased up to 2.7μ B for only 1% increment of interatomic distance. Furthermore, non-ferromagnetic state of fcc-Fe was observed at 1.8% decrement.
