Description
These ferrites were prepared from Fe2O3, MO oxides (M = Ba,Sr,Pb) and MeO oxides (Me = Mg,Mn,Co,Zn). Chemical compositions of the main barium ferrites (M = Ba) are represented in a ternary diagram. The structures of these various compounds (M,Y,W,Z,X,U) are closely related. The simplest one is the compound BaFe12O19 (M). Its crystal structure is similar to that of the mineral magnetoplumbite PbFe7.5Mn3.5Al0.5O19 (PbM12O19) (5). For this reason the hexagonal ferrites are also known as magnetoplumbite-type ferrites (called MP-type in this paper). When the Fe3+ ions are replaced by other trivalent ions, such as Al3+, Ga3+, another group of MP-type oxides, namely AB12O19 (A = Ba2+ or a large divalent ion; B = Al3+ or Ga3+) is obtained. In this paper, the authors briefly review ideal structure and major properties and uses, especially in the case of ferrites
