Formation of MnBi by Mechanical Alloying

In this report we demonstrate that mechanical alloying is an alternative process to produce the intermetallic compound MnBi. Magnetically MnBi powder is prepared from the elemental powders by mechanical alloying in a planetary ball mill and then solid-state reaction at a relatively low temperature. The MnBi powder was aligned in a magnetic field and isostatic pressed. The X-ray pattern of powder reacted clearly shows the intensity peaks of the MnBi phase. After annealing the magnetization was about 1.0×10$\text{}^{-4}$T m$\text{}^{3}$/kg
