Formation of Bose–Einstein magnon condensate via dipolar and exchange thermalization channels
Thermalization of a parametrically driven magnon gas leading to the formation of a Bose–Einstein condensate
 at the bottom of a spin-wave spectrum was studied by time- and wavevector-resolved Brillouin light scattering
 spectroscopy. Two distinct channels of the thermalization proces...

| description | Thermalization of a parametrically driven magnon gas leading to the formation of a Bose–Einstein condensate
at the bottom of a spin-wave spectrum was studied by time- and wavevector-resolved Brillouin light scattering
spectroscopy. Two distinct channels of the thermalization process related on dipolar and exchange parts of a
magnon gas spectrum are clearly determined. It has been found that the magnon population in these
thermalization channels strongly depends on applied microwave pumping power. The observed magnon redistribution
between the channels is caused by the downward frequency shift of the magnon gas spectrum due to the
decrease of the saturation magnetization in the course of injection of parametrically pumped magnons.
