文摘

Using X-ray powder diffractions, Mössbauer spectroscopy, and magnetic measurements, the effect of complexdopants (Co²⁺ + Ti⁴⁺) and (Bi³⁺ + Ti⁴⁺) on the fine structure and magnetic properties of M-type bariumhexaferrite prepared by hydroxide and carbonate precipitations has been studied. The distribution of cationsover five nonequivalent positions of barium hexaferrite with magnetoplumbite structure is discussed. It hasbeen shown that doped barium hexaferrite can be used for high-coercitivity data storage media.
