Resonant X‐Ray Magnetic Scattering Study of BaFe12O19 and BaTiCoFe10O19

Synchrotron diffraction studies have been carried out for single crystals of ferrimagnetic M‐type ferrites at the BL‐3A of the Photon Factory. Resonant x‐ray magnetic scattering (RXMS) and x‐ray magnetic circular dichroism (XMCD) at the Fe K edge were utilized to examine the magnetic order of 3d states through the hybridized 4p states. A magnetic satellite reflection of 0 0 8+(2/3) was observed for BaTiCoFe10O19 with the resonant enhancement The magnetic anomalous scattering factor f″m of BaFe12O19 was estimated as 0.23 at E = 7128.2 eV in the least‐squares procedure to use the difference of asymmetrical ratios. The crystal structure with spin arrangement has been determined for BaFe12O19, which coincides with the Gorter model.
