    Barium ferrite films applicable for data storage have been grown on sapphire substrate by pulsed laser deposition. BaFe12O19/Al2O3 films show a polycrystalline structure with high oriented perpendicular anisotropy. Large megneto-optic effects have been observed in the UV wavelength. The magnetic relaxation measurements reveal that the activation volume is only a fraction of the grain volume (Vact/Vgr=0.12). The angular studies of the remanene coercivity and the coercivity as well as the rotational hysteresis show that the curling is the appropriate mode for the magnetization reversal in the BaFe12O19 films.
