The effects of substituting Ba ions for Pb ions on low temperature preparation of barium ferrite thin films and on their magnetic properties were investigated. Ba1-XPbXFe12O19 thin films were deposited on a fused quartz substrate by an rf magnetron sputtering method. In order to control the composition of the deposited Ba1-XPbXFe12O19 films, several sintered BaFe2O4 chips and PbO chips were placed on the barium ferrite target. The film thickness was varied between 20 and 250 nm. As-deposited films were post-annealed at temperatures between 500 and 700°C for 5 hours in air.
Ba1-XPbXFe12O19 films with Pb content of 0.24 or above were well crystallized by post-annealing at 550°C for 5 hours in air. Ba0.65Pb0.35Fe12O19 film, especially, showed excellent magnetic properties, and its grains were small and uniform. As the film thickness of Ba0.65Pb0.35Fe12O19 film was decreased, its coercivity increased; its value reached 5.0 kOe at t = 50 nm. Moreover, the Ba0.65Pb0.35Fe12O19 film had little interaction between grains and high thermal stability of magnetization.
