Tunable magnonic spectra in two-dimensional magnonic crystals with variable lattice symmetry are studied using an all-optical time-resolved magneto-optical Kerr microscope. The magnonic mode profiles are interpreted in different lattices by micromagnetic simulations. A six-fold anisotropy is observed in the hexagonal lattice due to the variation of the magnetostatic stray field on the elements.
