Abstract
A magnetic device can include a tunnel bather and a hybrid magnetization layer disposed adjacent the tunnel barrier. The hybrid magnetization layer can include a first perpendicular magnetic anisotropy (PMA) layer, a second PMA layer, and an amorphous blocking layer disposed between the first and second PMA layers. The first PMA layer can include a multi-layer film in which a first layer formed of Co and a second layer formed of Pt or Pd are alternately stacked. A first dopant formed of an element different from those of the first and second layers can also be included in the first PMA layer. The second PMA layer can be disposed between the first PMA layer and the tunnel barrier, and can include at least one element selected from a group consisting of Co, Fe, and Ni.
