Figure 2

The surface formation energies determined by DFT calculations: side view of atomic structures for (a) FeGa alloy slab along [100], (b) FeGa alloy slab along [110], (c) FeGa alloy slab along [100] with Pt doping on its surface, (d) FeGa alloy slab along [110] with Pt doping on its surface. Orange regions correspond to the higher energy surfaces, whereas the green regions represent the lower energy surfaces. The blue regions refer to the interior of crystals.
