Outline of Final Research Achievements |
Atomic structural analysis and electronic structure of refined structural defects are studied in high-temperature annealed Fe3O4 thin films. The deviation from film stoichiometry, Fe and FeOx impurities and structural defects grown under non-equilibrium process were extremely reduced by high-temperature annealing in CO/CO2 atmosphere at 1000-1100oC. Existence of stable twin defect were found in the films although the nature of the superexchange interactions across the boundary is not changed in thin film form.
