We construct a model for magnetic topological insulators and study the edge states in its nano-ribbon. The model is a combination of the Kane-Mele and the double exchange models on a honeycomb lattice. We apply an inhomogeneous dynamical mean field model to the proposed model. We find different edge states in the paramagnetic topological, antiferromagnetic topological, antiferromagnetic topologically trivial and antiferromagnetic half-topological insulating states.
