From: Half-Metallic Behavior in Doped Sr2CrOsO6 Double Perovskite with High Transition Temperature
Left panel: The energy difference between PM and FM arrangement of Cr spins, plotted as a function of the valence electron count of Os ion, shown as black solid line.
The vertical lines mark the filling corresponding to the parent (solid, magenta) and various Na (red-solid, orange-dashed and brown-dot-dashed for Sr1.875Na0.125CrOsO6, Sr1.75Na0.25CrOsO6, Sr1.625Na0.375CrOsO6, respectively) and La doped compounds (green-solid, green-dashed and indigo-dot-dashed for Sr1.875La0.125CrOsO6, Sr1.75La0.25CrOsO6, Sr1.625La0.375CrOsO6, respectively) studied in present work. Both the Na-doped and La-doped compounds are half-metallic, while the parent compound with electron count of three, is insulating. Right panel: The spin polarization plotted as a function of the electron occupancy of Os ion. The vertical lines mark the parent and various Na and La doped compounds as in left panel.
