| 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 1.0×10-4T m3/kg. |
