Abstract :
The polycrystalline films of NiFe2O4, YIG, BaFe12O19, Ba2Zn2Fe12O22, or Ba3Co2Fe2O4were deposited on the Al2O3substrate by using the arc-plasma jet of an oxidizing gas of 90% oxygen gas and 10% argon gas. It has been found that those ferrite films which were prepared by this procedure possess saturation magnetizations less than and magnetic half-linewidths, ΔH, at 9 GHz, broader than those of the sintered ferrites. It has also been found that the properties of these films are highly sensitive to the partial pressure of the oxygen contained in the jet. Preparations of ferrite films with crystal orientation as well as films with induced anisotropy were also carried out.
