We calculate the nonlinear response of 2D topological antiferromagnetic materials. We model the systems by a tilted Dirac cone. We find that the purely intrinsic contribution is strongly affected by disorder corrections such as side jump, skew scattering and Berry curvature dipole like. We discuss the effect of time reversal and inversion symmetry in such a system.
