发明名称 Anisotropic rare earth sintered magnet and making method
摘要 An anisotropic rare earth sintered magnet has a tetragonal R 2 Fe 14 B compound as a major magnetic phase, wherein R is Nd or a mixture of Nd with at least one rare earth element. Grains of the compound phase have two crystallographic axes, c and a-axes aligned. The biaxially aligned magnet exhibits a coercivity Hc of at least 1.6 MA/m.
