Structural Aspects of the Bechgaard and Fabre Salts: An Update

摘要: We review structural aspects of the Bechgaard and Fabre salts in relationship with their electronic, magnetic superconducting properties. emphasize role bond charge modulations quarter filled organic stack various instabilities ground states exhibited by these salts. A special consideration is also devoted to influence anions methyl groups processes. In particular we point out importance achieving inter-stack coupling either direct or indirect (via polarization group cavities) interactions donors. this framework discuss disorders inhibition divergence high temperature order wave instability analyze modulation considering explicitly magnetization degrees freedom. consider stabilizing ordering pattern spin-Peierls transition relation adiabaticity phonon field. anion transitions more particularly process on electronic structure which results. show that texture ordered has consequences properties (TMTSF)2ClO4. Finally conclude essential implication freedom generic phase diagram
