Self-Generation of Chaotic Solitary Spin Wave Pulses in Magnetic Film Active Feedback Rings
2005
Physical Review Letters
Preserved Fulltext
The chaotic self-generation of short solitary spin wave pulses has been observed for the first time. The pulses were produced from parametrically excited spin waves in an yttrium-iron-garnet film in an active feedback ring under conditions where both three-wave and four-wave parametric processes were allowed. The power-frequency spectrum was broadband and chaotic.
