  • Abstract
    Hexagonal barium ferrites were prepared using the citrate method. Cobalt and titanium were added in the amounts x from 0.2 to 1.1 ion /f.u. related to the formula BaCoxTixFe12-2x O19. The heat treatment has been applied in three steps of 550°C/5 hrs, 850°C/2 hrs and 1100°C/2 hrs. The following magnetic properties have been achieved: Hc~80 kA/m, Js -120×10-6Tkg-1m3, and Jr-60×10-6 Tkg-1m3 in the composition for which x is equal to 0.5 ion/f.u. The magnetic parameters have been measured by the vibration magnetometer
