摘要：

We report photoemission studies of ultrathin films of the minority-spin conductor, Fe3O4 on a Cu(001) substrate. Fe films are deposited at room temperature and oxidized at 810 K in 10(-6) Torr O-2. For Fe films less than 2 ML thick, LEED and STM measurements show that oxidation produces mostly an FeO(111) while thicker Fe layers give Fe3O4(111). Photoemission reveals that there is a distinct electronic structure for these two phases. There are also significant differences between the electronic structures of ultrathin oxide films and those of corresponding bulk oxides. (C) 2000 American Institute of Physics.
