摘要
The Mn-Al permanent magnet is considered as a candidate to fill the gap between the best ferrite and Nd-Fe-B magnets. Anisotropy is hard to be obtained due to the formation of randomly oriented multi-variants of the ferromagnetic T-phase. In this work, an anisotropic single-variant is achieved through constrained martensitic transformation of the (Mn54Al46)(97)C-3 single crystal, which is based on the principle of magnetoelastic energy. This work guides a new approach for developing anisotropic Mn-Al permanent magnets.
