First-principles analysis of the effect of magnetic states on the oxygen vacancy formation energy in doped La${}_{0.5}$Sr${}_{0.5}$CoO${}_3$ perovskite

Wei Wei, Florian Fuchs, Andreas Zienert +2

Oxygen vacancies are critical for determining the electrochemical performance of fast oxygen ion conductors. The perovskite La${}_{0.5}$Sr${}_{0.5}$CoO${}_3$, known for its excellent mix…
