MnBi
MnBi is an intermetallic compound consisting of manganese and bismuth with the formula MnBi. It crystallizes in a hexagonal NiAs-type structure at room temperature, where manganese and bismuth occupy alternating lattice sites. The crystal arrangement leads to a strong uniaxial magnetic anisotropy along the c axis, which contributes to favorable magnetic stability and coercivity.
Magnetism in MnBi is ferromagnetic and the material exhibits a Curie temperature well above room temperature.
Processing and materials engineering play key roles in MnBi performance. It is typically synthesized by arc
Limitations and challenges include brittleness, oxidation sensitivity, and thermal stability concerns that complicate large-scale, long-term magnet
