Magnetic Properties of the MnBi Intermetallic Compound
A MnBi alloy containing over 90 wt% low-temperature phase (LTP) has been obtained by high-temperature sintering and magnetic purification. The coercivity of the bonded MnBi magnet increases with increasing temperatures. A coercivity of 2.0 T has been achieved at 400 K. The maximum energy product (BH) max; of the magnet is 7.7 MGOe (61 kJ/m 3) and 4.6 MGOe (37 kJ/m 3) at room temperature and 400 K, respectively. Neutron diffraction and magnetic data reveal a spin reorientation, which gives rise to low anisotropy fields and coercivity at lower temperatures for the LTP MnBi alloy. © 2001 American Institute of Physics.
