概要
- 論文の詳細を見る
By parallel pumping experiments antiferromagnetic spin-wave frequencies at theBrillouin-zone-boundary in (C.H,NH.).CuCl. have been measured as a function ofstatic magnetic fields below the spin-flop critical field. The experimental results are ingood agreement with the spin-wave theory which includes the effect of the magneticdipolar interaction. Measurements have been done at pumping frequencies from 7.7to 10.8 GHz and in the temperature range from 1 .4 to 2.6 K. The instability thresholdof the zone-boundary magnons is empirically described as H..= 0.30 X T"" Oe.
