FIG. 1.

Distributions of the component of the dynamic magnetization for the dots arrays for two interdot spacing (upper panel) and (lower panel). Note that to obtain plots of equal sizes in the two panels, the interdot distance is not in scale in the upper panel.

FIG. 2.

Sequence of BLS spectra for arrays of dots with different spacing at an incidence angle of . A magnetic field of is applied in-plane along the [10] direction of the dots lattice.

FIG. 3.

Experimental (full points) and calculated (continuous curves) mode frequency as a function of the interdot spacing . The orientation of the dc magnetic field with respect to the pattern is shown. The right side insets represent the magnetic mode profile for when the dots are almost noninteracting. Left side insets show the profiles of the modes at 10.8, 11.8, and for , resulting from the splitting of the fundamental mode.
