Abstract
A magnetic material composed of ε-InFeO(wherein 0<x≦0.30) crystal in which In is substituted for a portion of the Fe sites of the ε-FeOcrystal. The crystal exhibits an X-ray diffraction pattern similar to that of an ε-FeOcrystal structure and has the same space group as that of an ε-FeO. The In content imparts to the magnetic material a magnetic phase transition temperature that is lower than that of the ε-FeOand a spin reorientation temperature that is higher than that of the ε-FeO. The In content can also give the magnetic material a peak temperature of the imaginary part of the complex dielectric constant that is higher than that of the ε-FeO.
