Abstract
Element specific x-ray resonant magnetic scattering (XRMS) investigations were undertaken to determine the magnetic structure of the multiferroic compound, hexagonal . In the temperature range from 68 K down to 8 K the moments are aligned and antiferromagnetically correlated in the direction according to the magnetic representation . The temperature dependence of the observed intensity can be modeled assuming the splitting of ground-state doublet crystal-field levels of by the exchange field of . XRMS together with magnetization measurements indicate that the magnetic representation is below 8 K.
