The effects of annealing and the presence of the Pd buffer sublayer on the variation of magnetic properties (coercive force, squareness of magnetization curves, effective magnetic anisotropy constant) as well as remagnetization mechanisms and magnetic domain structure in multilayered Co/Pd thin films with perpendicular magnetic anisotropy observed for the thicknesses of Co 0.2–0.4 nm and Pd 0.6–1.0 nm have been investigated.
Keywords: Co/Pd thin films, perpendicular magnetic anisotropy, magnetization reversal mechanisms, structure of magnetic domains.
