The effects of perpendicular magnetic anisotropy (PMA) on a large enhancement of elastic light scattering (ELS) in ultrathin Co films were studied. The equilibrium position of magnetization in a Co film with a strong PMA was explained. Results showed that the maximum ELS intensity increased with the increasing Co thickness and the strong PMA realized Hcrit in the thicker Co films.
