Non-Stoichiometric Oxides: Structure, Texture, Thermodynamics and Magnetic Properties.

Abstract

The thermodynamics of the titanium-oxygen system was studied in the composition range of Ti3O5 to TiO2 at 1304K and the anion diffusion rates measured. There was no very marked trend in the diffusion coefficient with composition. A novel technique for studying oxidation/reduction mechanisms in transitional-metal oxides by direct observation in the electron microscope was developed. Studies of rutile-related systems were completed. It revealed the phenomenon of 'swinging CS planes,' where by rotation of the CS plane direction a continuous sequence of fully ordered structures of varying composition is passible. Magnetic susceptibility of the titanium oxide systems were studied as a function of composition and temperature. The magnetic anisotropy of single crystals in the same composition range has been measured.
