- 論文の詳細を見る
Antiferromagnetic resonance and parametric excitation of spin-waves at spin-flopcritical field in (C.H.NH.).CuCl. are studied by perpendicular-pumping technique.Nonlinear absorption which is attributed to the first-order Suhl instability is observedat twice the frequency of the spin-flop critical field resonance. Power dependence ofthe imaginary part of the susceptibility, z", shows the existence of the secondthreshold which indicates unstable growth of second group of magnon modes.
