The compound was synthesized by a sol-gel based procedure. Phase purity was confimred by XRD. The lattice was filled with oxygen in a high-pressure apparatus to obtain an oxygen stoichiometric compund with Fe4+ valence of iron, which was confirmed by Mössbauer spectroscopy. Analyst: Armin Feldhoff. Temperature: Room.
