Abstract

The coercivity and anisotropy of Fe-based superlattices have been found to be enhanced for Fe layer thicknesses from 3 to 30 atomic layers. Several nonferromagnetic metallic separation layers were used but the magnetic properties were found to be nearly independent of the material. Sandwich structures consisting of only one or two magnetic layers were prepared and it was found that size effects are important for dFe<60 Å. Magnetic coupling across large separations was also evident.
