Abstract
The magnetic moment reversal at each of the two inequivalent Nd sites in a single crystal of ferromagnetic is probed by dichroic resonant diffraction of circularly polarized x rays. The results, supported by theory, show that the -axis intrinsic magnetic stability of this superior permanent magnetic material arises predominately at one of the Nd sites (). The other site () undermines magnetic stability by favoring a magnetic moment orientation in the basal plane.
