A hybrid theory which combines the full nonlocal “exact” exchange interaction with the local spindensity approximation of density-functional theory is shown to lead to marked improvement in the description of antiferromagnetically coupled systems. Semiquantitative agreement with experiment i found for the magnitude of the coupling constant in La 2CuO4, KNiF3, and K2NiF4. The magnitude of the unpaired spin population on the metal site is in excellent agreement with experiment for La 2CuO4… CONTINUE READING
