Electromagnon on the Surface of Magnetic Topological Insulator

We investigate theoretically the electromagnon on the surfaces of the magnetic topological insulator thin films. It is found that when the magnetic asymmetry between the top and bottom surfaces is there, the ferromagnetic resonance is driven by the electric field which is two orders of magnitude mor...
