  Despite the various magnetic orders mediated by superexchange mechanism, the
existence of a long range antiferromagnetic (AFM) coupling is unknown. Based on
DFT calculations, we discovered an intrinsic long range AFM coupling in V doped
CuInTe$_2$. The AFM coupling is mainly due to the $p-d$ coupling and electron
redistribution along the interacting chains. The relatively small energy
difference between $p$ and $d$ orbitals and the small energy difference between
d orbitals of the dopants and that of stepping stone sites can enhance the
stability of this AFM configuration. A multi-bands Hubbard model was proposed
to provide fundamental understanding to the long range AFM coupling in
chalcopyrite diluted magnetic semiconductors(DMS).
