MN4C MANGANESE CARBIDE MAGNETIC SUBSTANCE AND MANUFACTURING METHOD THEREFOR

Title:

MN4C MANGANESE CARBIDE MAGNETIC SUBSTANCE AND MANUFACTURING METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2019/098716

Kind Code:

A1

Abstract:

A Mn4C manganese carbide magnetic substance and a manufacturing method therefor are provided. According to an embodiment, the Mn4C magnetic substance increases in saturation magnetization with the increasing of temperatures and thus can find applications in the field in which heat-induced magnetization reduction is harmful.
