摘要: We report a systematic investigation under pressure of spin susceptibility, nuclear relaxation rate and temperature dependence the resistivity in charge transfer salts TTF-TCNQ, TMTTF-TCNQ HMTSF-TCNQ. The very large dependences observed TTF-TCNQ family, which cannot be explained solely by band broadening point to picture magnetism governed properties one dimensional strongly correlated electron gas. An interpretation our data terms Hubbard model for itinerant provides an estimation ratio electron-electron repulsion width U/4t ≈ 1 at ambient pressure. effects correlations tend become weaker selenium compounds, particular HMTSF-TCNQ, or as is applied family.
