Abstract

The wave function describing a perfect antiferromagnetic ordering of spins at 0 K (the singlet projection of the Néel function) was proved to be not an eigenfunction of the exchange Hamiltonian: the long-range order is reduced as to permit a higher correlation between the nearest-neighbour spins.
