  • Magnetic iron oxide particle, magnetic material, and radio wave absorber
    Patent number: 8444872
    Abstract: Disclosed is a magnetic material having high Hc and High Curie point, which is capable of controlling such magnetic characteristics without requiring rare or expensive raw materials. Specifically disclosed is a magnetic material composed of particles of a magnetic iron oxide which is represented by the following general formula: ?-AxByFe2?x?yO3 or ?-AxByCzFe2?x?y?zO3 (wherein A, B and C each represents a metal excluding Fe and different from each other, satisfying 0<x, y, z<1), with ?-Fe2O3 as a main phase.
    Type: Grant
    Filed: May 30, 2008
    Date of Patent: May 21, 2013
    Assignees: The University of Tokyo, Dowa Electronics Materials Co., Ltd.
    Inventors: Shin-ichi Ohkoshi, Shunsuke Sakurai, Takenori Yorinaga, Kazuyuki Matsumoto, Shinya Sasaki
