摘要：

The effects of on-site Coulomb interaction in two-dimensional organic conductors, kappa-(BEDT; TTF)(2)X, alpha-(BEDT-TTF)(2)I-3 and (BEDT-TTF)(2)MHg(SCN)(4), have been studied within the Hartree-Fock approximation. If the strength of Coulomb interaction exceeds some critical value, various kinds of antiferromagnetic states appear and these phases have been classified on a phase diagram with two key parameters, which leads to a unified view on the ground states of this unique family.
