Abstract

Charge and spin-orderings in the 1/4-filled organic CT solids are of strong interest, especially in view of their possible relations to organic superconductivity. We show that the charge order (CO) in both ID and 2D CT solids is of the ...1100... type, in contradiction to mean field prediction of ...1010... CO. We present detailed computations for metal-insulator and magnetic insulator-insulator transitions in the θ-ET materials. Complete agreement with experiments in several θ systems is found. Similar comparisons between theory and experiments in TCNQ, TMTTF, TMTSF, and ET materials prove the ubiquity of this phenomenon.
