Abstract

The authors report on an x-ray resonant magnetic scattering measurement of ferromagnetic order, in the absence of an external magnetic field, using resonant dipole scattering at the Gd L-2 edge of GdMn2Ge2. Measurements of the ferromagnetic order of the Gd sublattice were accomplished using undulator radiation at the Advanced Photon Source and polarization analysis of the diffracted beam to significantly reduce the charge scattering background. The magnetic origin of the resonant intensity was confirmed by its temperature dependence and the angular dependence of the scattering cross section. (C) 2007 American Institute of Physics.
