Abstract
The vapour-deposition technique was employed to grow Fe - Pt multilayers at a deposition rate of 0.01 - 0.02 
. The thickness, periodicity, chemical composition, microstructure, and magnetic moment of the films were characterized and measured by various methods. It was found that, when the Fe layers were thinner than 3.4 nm, the Fe atoms grew in an fcc structure on the polycrystalline fcc Pt layers with a fixed thickness of 7.0 nm. The fcc Fe in the Fe - Pt multilayers exhibits ferromagnetic behaviour, and its magnetic moment can be as high as 
. The possible mechanism responsible for the modification of magnetic properties of fcc Fe is discussed.
