- Аннотация: Hexagonal gallium substituted barium ferrite BaFe11GaO19 with magnetoplumbite structure was produced by solid-state reaction. Given the X-ray diffraction (XRD) results, it was concluded that the samples can be characterized by a single-phase state. This paper presents the results of energy dispersive X-ray analysis (EDX), neutron diffraction, Mössbauer spectroscopy and vibrating-sample magnetometry (VSM). The XRD analysis based on Rietveld refinement demonstrated that BaFe11GaO19 samples crystallized in the P63/mmc hexagonal structure. According to the neutron diffraction data, the magnetic sublattice of barium hexaferrite BaFe11GaO19 corresponded to a crystal structure. According to the Mössbauer spectroscopy data, the substitution of gallium in barium hexaferrite occurred at 12k position. The magnetic properties investigation results indicated the possibility of gallium dopant cation substitution in the 12k position. A comparison of the calculated intensities of magnetic sublattice the neutronograms of BaFe12O19 and the experimental neutron diffraction data obtained from the BaFe11GaO19 sample allowed us to establish that the gallium ion occupies 12k positions with coordinates (0.33333, 0.16667, 0.10810) and (0.83333, 0.66667, 0.10810).
