[Wien] Why the antiferromagnetic structure of Cr is still cubic

Dear wien2k users

I have read that the antiferromagnetic ordering is accompanied with a
little structural distortion as in the case of NiO. This latter is
characterized by a distortion from NaCl to rhomboherdral structure; but for
the chromide Cr the structure is still cubic when there is a magnetic
transition from paramagnetic to antiferromagnetic state.

Best regards
