ENVELOPE SOLITONS AND MODULATION INSTABILITY OF SPIN WAVES IN MAGNONIC CRYSTALS

The paper describes results of experimental investigations on a formation of bright and dark envelope solitons with pulsed, monochromatic and two­frequency excitation of microwave spin waves in a magnetic film periodic structure – a magnonic crystal. The envelope solitons were excited at particular frequencies in the vicinity of magnonic bandgaps formed due to the Bragg resonance.
