The Magnetic Band-Structures of Ordered Pt<sub>x</sub>Fe<sub>1−x</sub>, Pt<sub>x</sub>Co<sub>1−x</sub>, and Pt<sub>x</sub>Ni<sub>1−x</sub> (x = 0.25, 0.50, and 0.75)
The electronic band structures of the ordered L1<sub>2</sub> and L1<sub>0</sub> phases of the Pt<sub>x</sub>M<sub>1−x</sub> (M = Fe, Co and Ni) alloys were investigated using spin-polarized density functional theory (DFT). The relative contributions of...

| Summary: | The electronic band structures of the ordered L1<sub>2</sub> and L1<sub>0</sub> phases of the Pt<sub>x</sub>M<sub>1−x</sub> (M = Fe, Co and Ni) alloys were investigated using spin-polarized density functional theory (DFT). The relative contributions of both itinerant (Stoner) and localized magnetism at the high-symmetry <i>k</i>-points were determined and discussed qualitatively. Significant directional effects were identified along the A and R directions of the L1<sub>0</sub> and L1<sub>2</sub> alloys, respectively, and are discussed in terms of charge channeling effects. |
