The site occupancies in permanent magnetic alloy Y_2(Fe_(0.95)Al_(0.05))_(14)B has been studied by means of neutron diffraction.The results from profile refinement show that Al enters the tetragonal structure of Nd_2Fe_(14)B and occupies the 4c and 8j_2 sites of the space group P4_2/mnm preferably.The relation between the site occupancies and the magnetic proper- ties is discussed preliminarily.

Neutron diffraction measurements on Nd2(Fe0,Si0 ,)14B at room temperature and 77 K were performed. Data analysis using profile refinement was carried out. The results show that at room temperature Si atoms occupy preferentially 4c, 8j, and I6k2 sites, and the magnetic moments of bath Nd and Fe are parallel to C-axis. At 77 K, the site occupations remain unchanged as in room temperature, while the calculated Nd magnetic moment direction has an angular deviation of 37.8 ° from C-axis.
