Dispersion Characteristics Of Magnetic Spatial Solitons On The Surface Of An Antiferromagnet

The dispersion characteristics of magnetic spatial solitons on an antiferromagnetic slab have been studied in this paper. The guided spatial soliton is on the plane interface between an antiferromagnetic slab and a semi-infinite linear dielectric. The distinguishing feature of the soliton is the existence of its frequency passband(s) and stopband(s) that can be switched into each other by varying the power.
