Sažetak
Low-dimensional organic conductors are well established as model systems for strongly correlated electron systems. The interplay of electronic, spin and lattice degrees of freedom together with changes in dimensionality result in a phase diagram, which may include antiferromagnetism, superconductivity, spin-density-wave ordering, spin-Peierls behavior and charge ordering. The position in the phase diagram can be tuned by external pressure, chemical pressure, via substituting the anion, and temperature. Commonly, the change in the dielectric properties associated with a phase transition is investigated by means of temperature dependent optical spectroscopy and electrical transport measurements. To extend the experimental access to the phase diagram, we establish a setup for electrical transport measurements up to 110 MHz in dependence of both, temeprature and pressure. Here, we present the overall setup and discuss the challenges when measuring dielectric properties on organic conductors under pressure. Additionally, we will present and discuss first results on the quasi-one-dimensional charge transfer salts (TMTTF)2X (X=BF4, ClO4) compounds at ambient pressure.
