Random Generation of Coherent Spin Wave Solitons From Incoherent Spin Waves

Abstract

This paper reports on the random generation of coherent envelope solitons from incoherent waves in a medium with an instantaneous nonlinearity, and specifically, in a magnetic thin film strip. One excites a propagating incoherent spin wave packet and observes the random appearance of spin wave envelope solitons from the propagating packet. The random solitons are as coherent as traditional envelope solitons, but both the peak amplitude and timing are random.
