Abstract
Fine Ba ferrite particles, suitable for coated perpendicular magnetic recording media, have been prepared. The particles, about 0.08 μm in average diameter, are thin hexagonal platelets with easy magnetization axes normal to their planes. Coercivity Hc is controllable in a wide range, without significant reduction in magnetization, by Co and Ti substitution. The measured temperature dependences of Hc and σs showed stable characteristics. Good squareness ratio was obtained from an orientation capability measurement.
