摘要: Excepting Co-Sm, which may be considered a mature technology, recent permanent magnet research has proceeded along four lines, (a) improvement of the properties Fe-Nd-B by alloying additions and processing, (b) exploration other alloy systems that feature tetragonal compound Fe14Nd2B type, such as Fe-Pr-B carbides, (c) systematic study new magnetic compounds, those based on Mn12Th structure, (d) characterization, sometimes elusive, phases are present in known contribute to coercivity.
