Реферат:	eng: The barium hexaferrite, BaFe12O19, microcrystals were obtained by the flux crystal growth method and were characterized by XRD, SEM, and TEM methods. XPS measurements were carried out on a powder sample. The binding energy differences between the O 1s and cation core levels, ΔBa = BE(O 1s) - BE(Ba 3d5/2) and ΔFe = BE(O 1s) - BE(Fe 2p3/2), were used to characterize the valence electron transfer on the formation of Ba-O and Fe-O bonds. The chemical bonding effects were considered on the basis of our XPS results measured for BaFe12O19 and the earlier published structural and XPS data for other Ba- or Fe-containing oxide compounds. The band structure of BaFe12O19 was calculated by spin-polarized DFT methods and compared to the valence band spectrum measured by the XPS method. © 2016 American Chemical Society.
