The Nd-Fe-B class alloy is the third generation of rare-earth permanent-magnet materi-al which has significant technological applications because it exhibits large magnetic ener-gy product. Compared with other permanent-magnet materials, Nd-Fe-B alloys are relative-ly easy to prapare and the raw materials of Nd, Fe and B are relatively economical. This note reports the first observation of Nd_2Fe_(14)B single crystal by means ofphotoelectron microscopy.
