首次在磁性薄膜中实现了微波磁包络孤子的自产生。在5.2 μ m厚的钇铁石榴石薄膜中产生了宽度为20 ns、载波频率为5.1555 GHz的静磁后向体波（MSBVV）孤子。膜和MSBVW传播结构是具有+4dB的总增益的环的一部分。在10兆赫的脉冲调制提供了中断的反馈和主动锁模，这是需要产生一个稳定的和连续的流的自生孤子脉冲。脉冲宽度和相位的测量证实了自产生脉冲的孤子性质。
The self-generation of microwave magnetic envelope solitons in magnetic films has been realized for the first time. Solitons with a width of 20 ns and a carrier frequency of 5.1555 GHz were generated for the magnetostatic backward volume wave (MSBVW) configuration in a 5.2 mu m thick yttrium iron garnet film. The film and MSBVW propagation structure were part of a ring with an overall gain of +4 dB. Pulse modulation at 10 MHz provided the interrupted feedback and the active mode locking which was needed to produce a stable and continuous stream of self-generated soliton pulses. Pulse width and phase measurements confirmed the soliton nature of the self-generated pulses.
