Crystallographic orientation of fine crystalline domains in magnet powder of Nd-Fe-Co-B-Ga produced by the hydrogenation-decompositlon-desorption-recombination (HDDR) method has been examined from their conventional selected area electron diffraction patterns. It was found that the c- and a-axes of domains (Nd2Fe14B-type: P42mnm) are aligned within 45° in solid angle, respectively. The correlated alignment of c-axes accounts for the magnetic anisotropy of the magnet powder.
