|Title:||Magnon Damping In Ferromagnetic Semiconductors Under Intense Radiation And Magnetic Fields|
|Abstract:||The magnon scattering by electrons in the simultaneous presence of radiation and magnetic fields is discussed. A kinetic equation is derived, and the rate of change of the magnon population is calculated. For circularly polarized radiation propagating parallel to the magnetic field it is found that multiphoton processes are dominant when the radiation frequency is near the electron cyclotron frequency. Furthermore, the damping rate is found to decrease exponentially as the radiation frequency approaches the electron cyclotron frequency. © 1977 The American Physical Society.|
