Abstract
We investigated the effect of substrate orientation and film thickness on the microstructure and magnetic properties of Sr- ferrite films grown on (0001) and 1102) sapphire substrates by pulsed laser deposition (PLD). The films grown on (1102) sapphire displayed a presence of various magnetic phases, including SrFe12O19 Fe2O3 and Fe3O4. The single hexaferrite phase was obtained in GIXRD at 1 degree and 5 degree for the thicker film. The structure measurements showed that all films on (0001) sapphire were single-phase c- axis oriented hexaferrites. The highest in-plane coercive force of 2.5 kOe was detected for the thicker film grown on (1102) sapphire. These films exhibit the highest in-plane squareness. The saturation magnetization of the films on (0001) sapphire rose when the film thickness was reduced.
