Ferroelectrics
As a model for ferromagnetism in an organic system, the spin interactions between two benzene-radical anions have been considered. Ab initio molecular-orbital calcuations for the energies of this dimer show that the ground state is a triplet for all separations of the benzene molecules, indicating a ferromagnetic interaction between spins on adjacent molecules. Furthermore, a three-parameter Hubbard model gives a quantitative fit to the energies of the 12 low-lying states. © 1989 The American Physical Society.
