摘要:
The invention refers to a method for manufacturing a at least 90% relative density of MnBi comprising permanent magnet (7), with a step of synthesizing (ST1a) an anisotropic low temperature phase (LTP) MnBi powder consisting of crystallite particles (1), whereby an aligned and pre-compacted powder is annealed below 628K such that a liquid Bi film (5) is formed around each of the MnBi particles (1).
