(a) BLS spectra taken at the Γ-point for the series S1 ADLs with different thicknesses applying a magnetic field μ₀H₀ = 0.1 T. (b) Calculated SW spatial profiles for the edge (E), the fundamental (F) and the fundamental-localized (F_loc) modes. The intensity of the color denotes the amplitude of the excitation, while the red and blue colors indicate opposite phase.
