Abstract: 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.
Keywords: cobalt, platinum, perpendicular magnetic anisotropy, vacuum annealing, irradiation, helium.
