OXIDATION AND ANNEALING EFFECT ON COBALT FILMS ON PALLADIUM(111)

Wookje Kim; S.-J. Oh; Tschang-Uh Nahm

We have investigated the effects of oxygen exposure on Co films grown on Pd(111) single crystal using magneto-optical Kerr effect and X-ray photoemission spectroscopy. Upon 300-langmuir oxygen exposure, the cobalt films are oxidized as CoO and a small amount of Co3O4, the latter being reduced to CoO on short heating at temperatures higher than 700 K. The ferromagnetic properties disappear by oxygen exposure. However, part of CoO decomposes into cobalt and oxygen on further annealing, and the ferromagnetic property reappears.
