Abstract :
In this paper we investigate the properties of nonlinear magnetic TM waves in the infrared frequency region on a plane interface between two uniaxial antiferromagnets. From the theoretical analysis and the numerical simulation, we find in this new guiding structure that there exist two thresholds: the frequency threshold and power threshold. All the incident waves should satisfy the two thresholds and then can steadily propagate. It is shown that the peak field position varies with the wave power. It is also revealed that the magnetic field amplitude on the interface is not power dependent but frequency dependent
