FIG. 1.

(a) Schematic of the longitudinal magneto-optic measurement setup. (b) Field emission SEM image of a corrugated Co layer deposited on a 2D colloidal crystal consisting of PS spheres with a diameter of . Insets: top, a magnified portion of the sample; middle, laser diffraction pattern obtained by normally impinging a laser beam (wavelength and spot size of 1 mm) on the sample; bottom, the angle between the principle axis of the 2D triangle lattice and the direction of the magnetic field. (c) Kerr hysteresis loops measured at different angles in steps of 10°. The nominal Co thickness on the spheres is 40 nm.

FIG. 3.

(a) Field emission SEM image of 40 nm Co layer deposited disordered colloidal spheres. The diameter of the polystyrene spheres is . The inset shows the laser diffraction pattern. (b) Kerr loops measured under different magnetic field directions within the sample plane.

Image of FIG. 4.
FIG. 4.

Field emission SEM image of 40 nm Co deposited on sample of short-range order. The diameter of the polystyrene spheres is . MOKE loop and laser diffraction patterns of the sample are shown in the inset.
