摘要：
The temperature dependence of the linewidth of the ferromagnetic resonance in re-entrant iron-based amorphous alloys (FexNi100-x)77B13Si10 (x = 7. 8, 9, 10 at. %) has been studied for the magnetic resonance frequency omega/2pi = 78 GHz and temperature 0.3-150 K. In the high-temperature range (4-30 K) the temperature dependence of the linewidth is described well by a universal exponential law. In the low temperature range (0.3-4 K) the line broadening is a linear function of the inverse temperature. The experimental results are discussed with allowance for two possible mechanisms of interaction of a spin ware with two-level systems in amorphous magnetics.
