CoTaZr/Pd multilayer with perpendicular magnetic anisotropy

CoTaZr/Pd multilayer with perpendicular magnetic anisotropy

We report a novel perpendicularly magnetized thin film [Co91.5Ta4.5Zr4/Pd]5 multilayer, which exhibits strong perpendicular magnetic anisotropy when grown on 5 nm of Pd and Ru seed layers. The Pd-seeded multilayer annealed at 300 °C shows an effective uniaxial anisotropy constant, Keff = 1.1 MJ m−3,...
