Oxygen-vacancy tuning of magnetism in SrTi₀₇₅Fe₀₁₂₅Co₀₁₂₅O₃-[delta] perovskite

Oxygen-vacancy tuning of magnetism in SrTi₀₇₅Fe₀₁₂₅Co₀₁₂₅O₃-[delta] perovskite

We use density functional theory to calculate the structure, band-gap, and magnetic properties of oxygen-deficient SrTi_{1−x−y}Fe_{x}Co_{y}O_{3−δ} with x=y=0.125 and δ={0,0.125,0.25}. The valence and the high or low spin states of the Co and Fe ions, as well as the lattice distortion and the band ga...
