AbstractMultilayer films consists of noble metal (Pd, Pt, Cu, Au, PdSi) and transition metal(Co, Ni, PdCo, PtCo, CoZr) layers were prepared by rf sputtering method on glass and/or MgO single crystal substrates. The perpendicular magnetic anisotropy was examined in relation to the magnetostriction, lattice misfits, crystallinity and crystal orientations. The results suggest that the perpendicular magnetic anisotropy in noble metal/PdCo alloy multilayers originates from the magnetoelastic energy of the PdCo layers under a stress due to the lattice misfits. In both Pd/Co and Pd/Ni multilayers, the anisotropy was found to depend on the crystal orientation, and the dependence is discussed from the view point of the magnetoelastic surface anisotropy.

Different Temperatures

The possibility of controlling the magnetic properties of multilayer periodic structures with perpendicular magnetic anisotropy based on cobalt and platinum films is investigated. Multilayer films consisting of layers 0.5–1.0 nm thick undergo to two types of impacts: vacuum annealing at different temperatures and irradiation with beams of helium ions. It was shown using transmission electron microscopy that irradiation with He+ ions with an energy of 30 keV leads to the mixing of the material of the layers. But the layer structure of the film is preserved during vacuum annealing. As a result of thermal annealing, the coercive force of the structure increases significantly. The coercivity of the helium ion irradiated films decreases to a change in the type of anisotropy from the perpendicular magnetic anisotropy to the “easy plane” anisotropy.
