Abstract
The stoichiometry and magnetic properties of reactively sputtered Fe-O /Ag multilayers were studied as a function of the Fe-O layer thickness . The thinnest Fe-O (50 Angstrom) layers were highly disordered. Howev er, when the thickness was increased to more than 100 Angstrom, well-c rystallized films comprised of a mixture of FeO and Fe3O4 were formed. The relative amount of FeO and Fe3O4 was thickness-dependent. Very th ick (more than 3500 Angstrom) films were essentially single-phase Fe3O 4. (C) 1998 Elsevier Science B.V. All rights reserved.
