|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 (SrFei2Oi9) films. The amorphous SrFeO underlayer was deposited at different temperatures in the range from room temperature to 70°C, while the SrFe12O19 film was deposited at 70°C. The SrFe12O19 films exhibited slightly perpendicular magnetic anisotropy by the rather higher coercivities in perpendicular direction (I-It ) than those for the in-plane direction (HII), due to the c-axis perpendicular orientation. The magnetization and coercivities of the SrFe12O 19 film increase, but the magnetic anisotropy (AH=H -HII) increases firstly and then decreases, as the SrFeO underlayer deposition temperature increases. © 2013 Elsevier BY.
