S. Jun et al., ORDINAL EXCITATION OF 3-MAGNON AND 4-MAGNON PROCESSES OF MAGNETOSTATIC SURFACE-WAVES IN YIG-FILMS, Journal de physique. IV, 7(C1), 1997, pp. 457-458
Ordinal excitations of three-magnon decay, modulation instability and
four-magnon decay processes of magnetostatic surface waves propagating
in a pure yttrium iron garnet film are investigated in accordance wit
h the relationship between the magnetostatic wave frequency and the in
ternal magnetic field. Onset of the modulation instability is realized
as a result of modification of magnetostatic surface wave dispersion
characteristics by a metallic ground plane.
