Change in the magnon distribution function in yttrium iron garnet during nonresonant parallel pumping

Nonresonant parallel pumping has been observed to change the distribution function of low-frequency spin waves. The effect is shown to be a consequence of a frequency redistribution of the magnons, in the direction of higher frequencies, in the rf field.
