Excitation of bright and dark envelope solitons for magnetostatic waves with attractive nonlinearity

摘要

Dark and bright envelope solitons have been generated from a single magnetostatic carrier wave with attractive nonlinearity. The solitons were formed through the mode beating of two microwave input signals with frequency separations of 3-30 MHz for an in-plane magnetized single crystal yttrium-iron-garnet film in the magnetostatic backward volume wave configuration. Numerical modeling based on the Ginzburg-Landau equation model gave good agreement with the data.
