| 简介 |
A ferrite magnet powder and a ferrite magnet exhibiting improved magnetic properties are provided at a reduced manufacturing cost. An application product and manufacturing methods thereof are also provided. An oxide magnetic material includes, as a main phase, a ferrite having a hexagonal M-type magnetoplumbite structure. The material includes : A, which is at least one element selected from the group consisting of Sr, Ba, Pb and Ca; R, which is at least one element selected from the group consisting of Y (yttrium), the rare earth elements and Bi; Fe; and B (boron). The constituents A, R, Fe and B of the material satisfy the inequalities of 7.04 at %≦A≦8.68 at %, 0.07 at %≦R≦0.44 at %, 90.4 at %≦Fe≦92.5 at % and 0.015 at %≦B≦0.87 at % to the sum of the elements A, R, Fe and B. |
