  • Oriented body, method for producing the same, device for producing the same, and magnetic recording medium
    Patent number: 11087792
    Abstract: There is provided an oriented body containing platinum group-substituted-6 iron oxide particles typified by Rh-substituted ?-iron oxide or Ru-substituted ?-iron oxide applicable to MAMR, MIMR, or F-MIMR system, and a technique related thereto, containing platinum group element-substituted ?-iron oxide particles in which a part of ?-iron oxide is substituted with at least one element of platinum group elements, as magnetic particles wherein the degree of orientation of the magnetic particles defined by the degree of orientation=SQ (direction of magnetization easy-axes)/SQ (direction of magnetization hard-axes) exceeds 5.0, and a coercive force exceeds 31 kOe.
