- 論文の詳細を見る
Magnetic interactions in organic conductors including magnetic anions, such as λ-(BETS)_2FeCl_4 and κ-(BETS)_2FeX_4[X=Cl and Br], are estimated from intermolecular overlap integrals ; the overlaps between anions afford J_<dd>, and those between anions and donors give J_πd. From this, the most stable spin alignments are decided, and such quantities as the Neel and Weiss temperatures, as well as the magnitude of spin polarization on the π-molecules are evaluated on the basis of the mean-field theory of πd-systems. The calculation is extended to several other πd-conductors, which are classified depending on the relative magnitudes of the direct dd- and indirect πd-interactions.
