The Enhanced Magnetization Observed in FE/mo Multilayers Deposited by Ion-Beam Sputtering

Abstract

AbstractFe/Mo multilayers, with varied Fe single layer thickness, tF, and Mo single layer thickness, tMO, were deposited by using a focusing ion-beam sputtering technique. Their structural and magnetic properties were studied. The periodic modulated structure was observed for all samples. An enhancement of magnetization over the value of bulk Fe was noticed for some samples. The change of lattice spacing of Fe layers, as a result of compress stress in the film plane, was considered to be responsible for the increase of the magnetization for Fe/Mo multilayers.
