Abstract

The experimental detection of a spin reorientation phase transition by means of Fe $K$ -edge x-ray magnetic circular dichroism (XMCD) is reported for ${Nd}_{2} {Fe}_{14} B$ . The temperature dependence of the XMCD signals at both Fe ( $K$ edge) and Nd ( $L_{2, 3}$ edges) is compared to that of the mutual orientation of the Fe and Nd magnetic moments derived from macroscopic magnetic measurements. The present study results in the experimental probe of the existence of a noncollinear arrangement of both Fe and Nd magnetic moments, throughout the spin reorientation transition.
