S. Obbade et al., A PRECISE CRYSTAL-STRUCTURE DETERMINATION .2. AN X-RAY 4-CIRCLE STUDYOF ND2FE14B AT 20 AND 290 K, Journal of alloys and compounds, 242(1-2), 1996, pp. 80-84
The crystal structure of Nd2Fe14B has been analysed at 20 and 290 K by
using the four-circle X-ray diffraction technique. The room temperatu
re tetragonal structure (space group P4(2)/mnm) has been accurately de
termined. At low temperature, the monoclinic distortion (space group C
m) proposed from a recent neutron diffraction experiment has been full
y confirmed.
