Composition and microstructural control of Sm2Fe17N3 powders: a promising candidate for next-generation permanent magnets

Abstract

Sm2Fe17N3 powders have drawn much attention in both fundamental research and industrial applications due to their excellent magnetic properties. The magnetic properties of Sm2Fe17N3 powders mainly depend on the composition and microstructure. Herein, the intrinsic and extrinsic magnetic properties of Sm2Fe17N3 powders are introduced, where the correlation between the composition, microstructure, and magnetic properties is discussed. Based on the correlation, we provide a detailed description of the synthesis methods and regulation strategies for Sm2Fe17N3 powders, aiming to promote the design and preparation of Sm2Fe17N3 powders with better magnetic properties.
