Abstract

Systems involving nonlinear media and their interaction with electromagnetic waves are potentially useful in various important practical applications. In the last decade or so, the availability of high-quality gyromagnetic crystal has led to a growing interest in nonlinear magnetic waves14. The interactions of gyromagnetic crystals with infrared waves or microwaves have drawn much attention. And many distinguishing features have been discovered in gyromagnetic waveguides. Recently. we have studied the frequency characteristics of magnetic spatial solitons on the surface of two-sublattice uniaxia! antiferrornagnetic crystal241. The striking feature of the soliton is the existence of the frequency passband(s) and stopband(s) that can be switched into each other by varying the power. In this article we studied the TE (transverse electric) surface waves, in the region of microwave frequency, on the interface between a linear ferromagnet and a two sublattice Un iaxial nonlinear antiferromagnet.
