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. WПоказать полностьюdoping 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.
