Fe-Co films deposited in an alternating multilayer structure by a magnetron dc-sputtering method have an artificial superlattice structure with crystallographic coherence between constituent layers. The films are bcc with (110) planes parallel to the film surface. The lattice constant of films is smaller than for bulk Fe and decreases linearly to about 2.81 Å with increasing Co layer thickness. The films are ferromagnetic with an easy magnetization direction in the film plane. The magnetization of multilayer films in comparison with that of Fe-Co alloy films with similar compositions is smaller for films with a thicker Fe than Co layer, and larger for films with a thinner Fe than Co layer. The large magnetization of Fe-Co films is attributed to the large magnetization of bcc-Co in comparison with that of bulk hcp Co.
