The periodical ordering of the asphericity of 4f charge density at holmium single crystal

This work presents X-ray scattering studies of the 2τ satellite peaks related to the periodical ordering of the asphericity of the 4f charge density of the metalic pure holmium single crystal. The thermal evolution of these satellite peaks demonstrates that the aspherical helical ordering has the same behavior as the magnetic helical ordering in the antiferromagnetic and ferromagnetic phases.
