The determination of the easy axis of magnetization at variable temperature
s using X-ray powder diffraction in an external magnetic held is described.
The method is based on the observation of the preferred orientation induce
d by aligning the magnetic grains along the field direction of a sample hol
der consisting of a permanent Sm2Co17 based magnet. (C) 1999 Elsevier Scien
