Abstract
Using X-ray lithography and ion beam etching we have patterned microme ter-sized square lattices of round dots, out of Au/Co/Au(111) films wi th perpendicular easy magnetization axes. The magneto-optical Kerr rot ation shows strong variations versus the diffraction order, the light polarization direction and the ratio of film to background reflectance , particularly when the lattice spacing is high compared with the dot size. This reveals an important interplay between diffraction and magn eto-optics.
