FIG. 1.

Brillouin spectrum of the hexagonally ordered array of nanowires recorded at an applied field of . The peaks are due to the two quantized spin-wave modes. The experimental data are denoted by dots. The spectrum is fitted with two Lorentzian functions (dotted curves) and a background (dashed curve), and the resulting fitted spectrum is shown as a solid curve.

FIG. 2.

Magnetic-field dependence of the frequencies of the three lowest-lying spin-wave modes in nanowires. The azimuthal quantum numbers , 2, and 3 label the spin-wave modes of an isolated nanowire. The experimental data are denoted by symbols while the calculated frequencies are represented by solid (collective spin-wave modes) and dashed (isolated nanowire) curves. The depression of the lowest-lying collective spin-wave branch relative to that of the isolated nanowire is illustrated in the inset, which displays an enlarged portion of the plot.
