| titleOfInvention | Cobalt-coated needle iron magnetic iron oxide particles |
| abstract | The cobalt-coated needle-shaped magnetic iron oxide particles of the present invention have an average major axis diameter of 0.15 to 0.50 m andn n n (In terms of P) of 0.05 to 1.0% by weight, based on the weight of the cobalt-coated needle-like iron oxide particles as seed crystal grains,n n n A spinel ferrite layer containing cobalt formed on the surface of seed crystal grains as an inner layer; andn n n And as the outer layer, a coating layer containing a hydroxide of magnesium formed on the surface of the spinel ferrite layer.n n n The magnetic iron oxide particles of the cobalt-coated needle-like iron have a small change in coercive force with temperature and a small switching field distribution, and thus are suitable as magnetic materials for magnetic recording media. |
