Schematic views of geometries used in the experiment. (a) -to- geometry and (b) -to- geometry.
(a) Energy scans for the (0 0 10) reflection at 60 and , and the differences of the intensities between two temperatures with -to- geometry and (b) -to- geometry. The solid line represents the polarization factor of the analyzer, . (c) Temperature dependence of the integrated intensity of the (0 0 10) reflection with the -to- geometry. The inset plots where is the integrated intensity of the magnetic reflection obtained by subtracting the measured intensity above the transition temperature from the intensity at each temperature and is the estimated magnetic intensity at . This is proportional to the local magnetization of Gd. The line represents Bloch’s law .
Scattering angle dependence of magnetic intensity. The solid line represents theoretical prediction for a moment direction aligned along the axis .
