  • Publication number: 20090071572
    Abstract: The alloy material having fine grain size, which is suitable for the mass-production, the magnetic material of bulk having single phase and homogeneous composition and manufacturing method of them are offered. The alloy material comprises a plurality of phases different in composition, the grain size of each phase is 20 ?m or less, and the composition as a whole is equal to an NaZn13 type La(FexSi1-x)13 compound. When the alloy material is heat treated, various kinds of elements are sufficiently diffused in a short time, and magnetic material comprising an La(FexSi1-x)13 compound having an NaZn13 type crystal structure of a single phase and homogeneous composition can be efficiently obtained.
