WebThe high energy around 33 GHz band corresponded to the light scattering due to the phonons in the glass substrate, which is insensitive to magnetic field alternation. Conversely, the low energy band below 7 GHz shifts with the field from 210 to 235 mT, as an indicative of magnon generation in the magnetic V(TCNE)x film during light scattering. WebMar 1, 2015 · The intensity, polarization selection rules, and the magnetic field dependence of the second-order light scattering from spin-wave excitations (i.e., two-magnon Raman spectra) are captured by the theory developed by Fleury and Loudon [21], which has achieved remarkable success in the localized moment limit [21], [22], [23], [24], [25].
