摘要：

Anisotropic Mn Bi/Nd Fe B（Mn Bi contents of0 wt%, 20 wt%, 40 wt%, 60 wt%, 80 wt%, and 100 wt%）hybrid bonded magnets were prepared by molding compression using Mn Bi powders and commercial hydrogenation disproportionation desorption and recombination（HDDR） Nd Fe B powders. Magnetic measurements at room temperature show that with Mn Bi content increasing, the magnetic properties of the Mn Bi/Nd Fe B hybrid bonded magnets all decrease gradually, while the density of the hybrid magnets improves almost linearly. In a temperature range of 293–398 K, the coercivity temperature coefficient of the hybrid magnets improves gradually from-0.59 %áK;for the pure Nd Fe B bonded magnet to-0.32 %áK;for the hybrid bonded magnet with 80 wt%Mn Bi, and the pure Mn Bi bonded magnet exhibits a positive coercivity temperature coefficient of 0.61 %áK;.
