- 論文の詳細を見る
Interrelationship among electronic structures of α-(ET)_2I_3, (ET)_2MHg(SCN)_4 and _K-(ET)_2X is studied theoretically. The effects of on-site Coulomb interaction are investigated at absolute zero within the Hartree-Fock approximation. If Coulomb interaction exceeds some critical value, various kinds of antiferromagnetic states emerge, which depend crucially on the transfer integrals between ET molecules in a unit cell. The above three types of materials are classified on the axes of two transfer integrals, leading to a unified view of the compounds.
