Structure and magneticproperties of barium hexaferrite BaFe10CoNiO19 films

We prepared Co-Ni doped BaFe10CoNiO19 films on the quartz glass substrates by ultrasonic spray pyrolysis with different molarities. The precursor was prepared by dissolving barium nitrate (Ba(NO3)2), iron nitrate (Fe(NO3)3.9H2O), cobalt nitrate (Co(NO3)2.6H2O), nickel sulfate (Ni2SO4.7H2O) in 50 mL of distilled water. Precursor solution was sprayed onto the cleaned quartz plates previously heated to 150 – 200°C, using a sprayer and argon as carrier gas. For crystallization the films were annealed in a furnace at a temperature 1000°C for3 hour in atmosphere ambient. By scanning electron microscopy (SEM), the barium hexaferrite BaFe10CoNiO19 films shows agglomeration and the average diameter of particles less than1 μm. We believed, the structure of barium hexaferrite BaFe10CoNiO19 films change due to Co-Ni existence. Therefore, the magnetic properties deteriorate by incorporation of Co-Ni into the structure of barium hexaferrite BaFe10CoNiO19.
