Abstract
A thin amorphous SrFeO underlayer on Si(100) substrate was pulse laser deposited as an underlayer for the growth of c-axis perpendicularly oriented strontium hexaferrite (SrFe12O19) films. The amorphous SrFeO underlayer was deposited at different temperatures in the range from room temperature to 700 °C, while the SrFe12O19 film was deposited at 700 °C. The SrFe12O19 films exhibited slightly perpendicular magnetic anisotropy by the rather higher coercivities in perpendicular direction (Hcâ¥) than those for the in-plane direction (Hc||), due to the c-axis perpendicular orientation. The magnetization and coercivities of the SrFe12O19 film increase, but the magnetic anisotropy (ÎHc=Hcâ¥âHc||) increases firstly and then decreases, as the SrFeO underlayer deposition temperature increases.
