Abstract :
The FMR linewidth is studied experimentally for reentrant magnets (FexNi100-x)77B13Si10 in the temperature interval 0.3 K<T<200 K, for frequencies 68 GHz<hω/kT<78 GHz. The low temperature, interval down to T≈0.3 K is thoroughly explored. The linewidth behavior agrees qualitatively with the theoretical model
