On the possible instabilities in the ferromagnetic resonance due to non-linear relaxation

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

The case of ferromagnetic resonance with effective frequency shift and effective linewidth dependent on excitation will be dealt with. The stability of steady state solutions will be proved and the general instability conditions will be deduced for the case considered. Afterwards, the transverse resonance relaxation caused by a system of two-level ions will be investigated. The steady solutions and their stability will be discussed for ions with identical doublet splitting as well as for a system with fluctuating value of splitting frequency. The general considerations will be illustrated by numerical calculations for various values of frequency and h.f. field intensity parameters.
