Fe/Tb multilayers with various Fe layer thickness and fixed Tb layer thickness wereprepared by e-beam alternate vapor deposition. Analyses of the microstructure of thesefilms show that the magnetic performance is strongly affected by the interface struc-ture. Fe in the films evolved to amorphous phase and the Fe/Tb interface becameindiscernible with decreasing Fe thickness. At the same time, the film was observedto perform superparamagnetically, which is quite different from the ferromagnetic be-havior of Fe/Tb multilayers that have sharp Fe/Tb interface. Our work shows thatthe interface roughness has strong influence to the properties of magnetic multilayers.

Magnetic multilayers are artificially structured materials made of ultrathin films of two different mate- rials,alternately ferromagnetic and non-ferromagnetic.They exhibit new magnetic properties differ- ent from those of bulk materials.We review the magnetic properties of metallic magnetic multilayers and focus on interface magnetic anisotropy,giant magnetoresistance and interlayer couplings,which are of great promise for applications to high density magnetic storage.
