摘要：

It is pointed out that the peculiar antiferromagnetic order found in NdNiO3 and the ferromagnetic coupling of the Ni2+ in the Li layers of Li1-xNi1+xO2, x less than or equal to 0.08, to the ferromagnetic NiO2 sheets can be accounted for by a shift of the Ni3+-O2-=Ni2+-O- equilibrium to the right, which introduces a magnetic coupling carrying the sign of covalent exchange rather than superexchange.
