Abstract:Recently MnBi magnetic material attracts a large attention due to its potential for high-temperature permanent magnetic applications. Although its sponatenous magnetization is moderate, Ms ~ 8.2 kG74 emu/g but its large coercivity, iHc > 10 kOe, which results in the theoretical value of energy product (BH)max ~16.8 MGOe. The MnBi single phase is difficult to be prepared by using conventional techniques, such as the arc-melting, melt-spinning and sintering because of the big difference between the melting te… Show more
