Evaporation of Fe and Co at a residual O 2 pressure of 10-5to 10-4Torr yielded magnetic films of high coercivities up to 500 Oe and magnetizations of about 1000 EMU/cm3. While the Co films were continuously deposited in the O 2 atmosphere, a sandwich structure of Fe and Fe 2 O 3 was formed by intermittently altering the evaporation conditions. Both kinds of films were produced in the same geometrical arrangement. The Fe/Fe 2 O 3 films showed shape anisotropy caused by the oblique incidence deposition, while no uniaxial anisotropy was observed on the Co films. For both, Co films and Fe/Fe 2 O 3 sandwich films, it was possible to adjust the magnetic properties within a certain range. In both cases the coercivity increased considerably by annealing at 200°C.
