内容記述 | A new type acicular BaCoxTixFe12-2xO19(X=0-1.0) particle and their coated films were prepared. The homogeneous mixtures of α-FeOOH, Ba(OH)2・8H2O, Co acetylacetonate and Ti acetylacetonate were sintered at 900℃ for 3hrs and then quenched. The aspect ratio of about 10-15 didn't depend on the amount of the substitution, X. The coercive force linearly decreased with the increase of X. As the sample of X=0.7 had the coercive force of about 1KOe, it is available for the present magnetic recording medium. The magnetization of these samples was unchanged with X until X=0.7. The mixture of the acicular particles of X=0.7, dispersing agent and binder resins was coated on the polyester film in the magnetic field of 7KOe perpendicular to the film. It was confirmed that the long axis of the acicular particles was parallel to the base film by the TEM observation of the cross-section of the coated film. The magnetic anisotropy of acicular BaCoxTixFe12-2xO19 film is in the direction perpendicular to the filrn. The acicular hexagonal ferrite particles is applicable to a perpendicular magnetic recording medium. |
