FIG. 1.

Sketch of the sample arrangement and block-diagram of the experimental setup.

FIG. 2.

(a) Field-swept experimental spectrum recorded at a microwave frequency of 3.8 GHz. Filled curves represent data recorded with the laser spot fixed at the sample center. Points correspond to data obtained by integration over the sample. (b) The corresponding curves obtained using OOMMF simulations. In all graphs the out-of-plane precession angle m  = M /M s is shown.

FIG. 3.

Frequencies of the spin-wave modes in a square sample with different number of antinodes. Note partial degeneracy of different modes. Inset: calculated spatial profiles of the pattern formed by a linear combination of the (1,5)- and (3,7)-modes and (1,7) and (3,9) modes.

Image of FIG. 4.
FIG. 4.

Left, experimental spatial profiles for the fundamental (1,1)-mode as well as for the DE (3,1), (5,1), and (7,1) modes, respectively. Right, corresponding spatial profiles obtained via simulation with OOMMF. The resonance field for each mode at 3.8 GHz is indicated.

Image of FIG. 5.
FIG. 5.

Left, experimental spatial profiles for the BV (1,3), degenerate (1,5), and degenerate (1,7), modes, respectively. Right, corresponding spatial profiles obtained via simulation with OOMMF. The resonance field for each mode at 3.8 GHz is indicated.

Image of FIG. 6.
FIG. 6.

Experimentally recorded spatial profiles of the fundamental (1,1) mode. Note the X-like network of straight lines. The white lines correspond to the calculated value of the critical angle θc = 57 °.
