Abstract
Synchrotron radiation has been utilized for producing the intensity difference in resonant X-ray magnetic scattering (RXMS) of ferrimagnetic BaTiMnFe10O19 at the BL-6C beamline of the Photon Factory. The energy of incident X rays was selected as E = 7.1245 keV within the threshold region of Fe K absorption edge from the observation of X-ray magnetic circular dichroism (XMCD). An asymmetrical ratio between RXMS intensities in left- and right-handed circular polarizations makes it possible to determine the magnetic crystal structure. The residual functions of Σ(ΔRobs - ΔRcalc) 2 related to the ratio were used to evaluate magnetic moments for individual Fe sites in the least-squares calculations, refined as multiplicity parameters of atomic scattering factor. The canting angles of the spin of Fe atoms have been derived for BaTiMnFe10O19, which are 90°, 0° and 31° for octahedral 2a, 4f2 and 12k sites, respectively.
