摘要：
The present invention relates to a magnetic material containing a magnetic alloy particle having an ordered crystal structure. The magnetic material according to the present invention is the one composed of a magnetic alloy particle having crystal magnetic anisotropy and being composed of an FePt alloy, a CoPt alloy, an FePd alloy, a Co3Pt alloy, an Fe3Pt alloy, a CoPt3 alloy, an FePt3 alloy, or the like, and a silica carrier covering the magnetic alloy, in which the silica carrier contains an alkali-earth metal compound such as an oxide, hydroxide or silicate compound of Ba, Ca, or Sr. The magnetic material according to the present invention is excellent in magnetic properties such as coercive force.
