FERROMAGNETIC PARTICLE POWDER, METHOD FOR PRODUCING SAME, ANISOTROPIC MAGNET, AND BONDED MAGNET |
摘要 |
<p>The present invention is a ferromagnetic particle powder constituted of 70% or more Fe16N2compound phase according to the Mossbauer spectrum. Specifically, the present invention relates to a ferromagnetic particle powder characterized by containing one or more metal elements (X) selected from Mn, Ni, Ti, Ga, Al, Ge, Zn, Pt, and Si in a molar ratio to Fe of 0.04 - 25% and having BHmax for the ferromagnetic particle powder of 5 MGOe. The present invention further relates to a method for producing the same and an anisotropic magnet and bonded magnet in which this ferromagnetic particle powder is magnetically oriented. This ferromagnetic particle powder can be produced industrially and is a Fe16N2 particle powder that contains a different metal element having a large BHmax.</p> |
