Abstract
Official abstract text for this publication.
Disclosed are an MnBi sintered magnet exhibiting excellent thermal stability as well as excellent magnetic characteristics at high temperature, an MnBi anisotropic complex sintered magnet, and a method of preparing the same.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of preparing a MnBi-based sintered magnet, the method comprising: (a) preparing a non-magnetic phase MnBi-based alloy; (b) subjecting the non-magnetic phase MnBi-based alloy to heat treatment to convert into a magnetic phase MnBi-based alloy; (c) pulverizing the magnetic phase alloy to prepare MnBi hard magnetic phase powders; (d) mixing the MnBi hard magnetic phase powders with a low-melting point metal powder into a mixture; (e) mold…
