Propagation Effects in the Spin-Wave Spectrum of the Ferromagnetic Thin Film

Figure 6

Two regions in the uniform zone for bcc(110) surface cut and ferromagnetic NNN interactions, with normal () and reverse () mode order in the spin-wave spectrum. The boundary between the regions shifts with growing as shown by the arrow. For no NNN interactions () the reversal domain does not occur (its boundary amounts to the segment -).
