(color online) Orbital-decomposed DOS for the interfacial (a) Fe atom in the Fe/MgO interface, (b) Fe atom in the CoFe/MgO interface, and (c) Co atom in the Fe/MgO interface. Details around for the state are shown in the inset. The red and black lines correspond to the biaxial strains of 0% and 3.5%, respectively.
