Abstract
Acicular barium ferrite fine particles doped with Co 2+ ions and Ti 4+ ions were prepared by a conventional sintering method. We investigated particle fine structure and magnetization mechanism of the acicular BaCo X Ti X Fe 12− 2X O 19 ( X = 0–1.0) fine particles. By TEM observation for the acicular BaCo X Ti X Fe 12− 2X O 19 fine particles, it was clarified that the particles consisted of some grains and their c-axis was aligned along the short axis of the acicular particle. Moreover, magnetic tapes coated with these particles and binders under a magnetic field of 7 kOe were prepared to investigate their magnetization mechanism. It was confirmed that the magnetization mechanism of the acicular BaCo X Ti X Fe 12− 2X O 19 fine particles was rotation magnetization by the measurement of the angular dependence of their coercivity.
