(a) Spin-wave resonance spectra of the elements with different h . The blue circular, red pentagram, green diamond-shaped, magenta square, and black triangle dots denote the EM, F, 2-BA, 4-BA, and 2-DE modes, responsively. (b) Spatial profiles of the z -component of the dynamical magnetization of EM and F modes for different h . (c) Frequency evolution with h for degenerate S-EM and AS-EM modes.
