Abstract
The surface oxidation processes of thin films of magneto-optic materials, such as the rare- earth transition metal alloys, have been studied starting in ultrahigh vacuum environments using surface analysis techniques, as a way of modeling the oxidation processes which occur at the base of a defect in an overcoated material at the instant of exposure to ambient environments. Materials examined have included FeTbCo alloys, as well as those same materials with low percentages of added elements, such as Ta, and their reactivities to both O2 and H2O compared with materials such as thin Fe films coated with ultrathin adlayers of Ti. The surface oxidation pathways for these materials are reviewed, and XPS data presented which indicates the type of oxides formed, and a critical region of Ta concentration which provides optimum protection.
