In this work, we construct a generalized Kane model with a new coupling termbetween itinerant electron spins and local magnetic moments ofanti-ferromagnetic ordering in order to describe the low energy effectivephysics in a large family of anti-ferromagnetic half-Heusler materials.Topological properties of this generalized Kane model is studied and a largevariety of topological phases, including Dirac semimetal phase, Weyl semimetalphase, nodal line semimetal phase, type-B triple point semimetal phase,topological mirror (or glide) insulating phase and anti-ferromagnetictopological insulating phase, are identified in different parameter regions ofour effective models. In particular, we find that the system is always driveninto the anti-ferromagnetic topological insulator phase once a bulk band gap isopen, irrespective of the magnetic moment direction, thus providing a robustrealization of anti-ferromagentic topological insulators. Furthermore, wediscuss the possible realization of these topological phases in realisticanti-ferromagnetic half-Heusler materials. Our effective model provides a basisfor the future study of physical phenomena in this class of materials.
