Surface spin waves in coupled easy-axis antiferromagnetic films

We present results of studying properties of surface spin waves in vertically coupled antiferromagnetic films with easy-axis anisotropy. The dispersion curves and frequency region of the existence of the surface magnetostatic waves are obtained using theoretical model for different antiferromagnetic materials. This study was carried out by solving the dispersion relation for the surface magnetostatic waves. Behavior of two types of dispersion curves on the value of coupling parameter is investigated. We conclude, that results have potential applications for antiferromagnetic THz spintronics.
