Structural Distortion Stabilizing the Antiferromagnetic and Insulating Ground State of NiO

Structural Distortion Stabilizing the Antiferromagnetic and Insulating Ground State of NiO

We report evidence that the experimentally observed small deformation of antiferromagnetic NiO modifies the symmetry of the crystal in such a way that the antiferromagnetic state becomes an eigenstate of the electronic Hamiltonian. This deformation closely resembles a rhombohedral contraction, but d...
