摘要：

Modulational instability of high-intensity spin waves exhibiting amplification is studied in magnetic films under conditions of three-magnon decay. The mechanisms for this effect and for randomization of the envelope under self-modulation are identified. (C) 1999 American Institute of Physics. [S1063-7842(99)01808-5].
