Two-dimensional microwave nonlinear spin-wave pulses in in-plane confided magnetic films

摘要

Spin-waves microwave envelope solitons in yttrium iron garnet films attract attention since their discovery more than 25 years ago [1]. The unique capability of solitons to preserve their shape during propagation makes them promising for many applications, in particular for microwave pulse train and comb frequency generation. In the subsequent experimental studies it was found that the most suitable spin-wave configuration for bright envelope solitons is the case of backward volume magnetostatic spin wave (BVMSW), propagating along the direction of static magnetic film applied in the film plane [2].
