PARAMETRIC EXCITATION OF SPIN-WAVES THROUGH SPIN-FLOP CRITICAL FIELD RESONANCE IN (C2H5NH3)2 CuCl4

Abstract
Parametric excitation of spin-waves in antiferromagnetic (C2H5NH3)2 CuCl4 has been studied by the perpendicular-pumping technique. Nonlinear absorption which is attributed to the first-order Suhl instability is observed at twice the frequency of the spin-flop critical field resonance.
