Аннотация: Tungsten-substituted barium hexaferrite single crystals were grown by flux method at 900-1260 °C. Crystals of BaFe12-xWxO19 with x up to 0.06 were obtained. The W content in the crystals can be controlled via the W content in the flux. Upon increase of the tungsten concentration the cell parameters and magnetic properties change. W doping results in an increase of coercive force from 331 to 489 Oe, which makes these materials prospective for permanent magnets. The substitution results in a small reduction of the Curie temperature from 455 to 453.1 °C and in a decreasing saturation magnetization at room temperature from 71 to 64 emu/g for powder samples. © 2015 Elsevier B.V.
