摘要：

Thin films of NiFe2O4, CoFe2O4, Ni0.5Zn0.5Fe2O4, and BaFe12O19, deposited at temperatures higher than 500 degrees C are isotropic and polycrystalline, the thickness (25 nm up to 1.5 mu m), the grain size (50 nm to 1 mu m) and surface roughness (1 to 100 nm) depending upon deposition parameters. Saturation magnetizations are close to the bulk values, but coercivities are rather high: up to 500 Oe for Ni-ferrites and more than 3 kOe for the hexaferrite.
