“…Typical contact resistances were ≤ 10 Ω. Owing to the large in-plane vs. out-of-plane resistivity anisotropy in these materials and the irregular shape of the crystals, an accurate determination of the in-plane resistivity ρ is very difficult, see e.g. 15,16,17 . As pointed out in these references, those in-plane data derived from a standard measurement geometry with four contacts on the same face of the crystal, almost always contain a significant interlayer component ρ ⊥ .…”

Resistivity studies under hydrostatic pressure on a low-resistance variant of the quasi-two-dimensional organic superconductorκ−(BEDT−TTF)2Cu[N

Resistivity measurements have been performed on a low (LR)-and high (HR)-resistance variant of the κ-(BEDT-TTF)2Cu[N(CN)2]Br superconductor. While the HR sample was synthesized following the standard procedure, the LR crystal is a result of a somewhat modified synthesis route. According to their residual resistivities and residual resistivity ratios, the LR crystal is of distinctly superior quality. He-gas pressure was used to study the effect of hydrostatic pressure on the different transport regimes for both variants. The main results of these comparative investigations are (i) a significant part of the inelastic-scattering contribution, which causes the anomalous ρ(T ) maximum in standard HR crystals around 90 K, is sample dependent, i.e. extrinsic in nature, (ii) the abrupt change in ρ(T ) at T * ≈ 40 K from a strongly temperature-dependent behavior at T > T * to an only weakly T-dependent ρ(T ) at T < T * is unaffected by this scattering contribution and thus marks an independent property, most likely a second-order phase transition, (iii) both variants reveal a ρ(T) ∝ AT 2 dependence at low temperatures, i.e. for Tc ≤ T ≤ T0, although with strongly sample-dependent coefficients A and upper bounds for the T 2 behavior measured by T0. The latter result is inconsistent with the T 2 dependence originating from coherent Fermi-liquid excitations.

Abstract. We present a review of quasi-two-dimensional organic superconductors. These systems exhibit many interesting phenomena, including reduced dimensionality, strong electron-electron and electron-phonon interactions and the proximity of antiferromagnetism, insulator states and superconductivity. Moreover, it has been possible to measure the electronic bands of many of the organics in great detail, in contrast to the situation in other well-known systems in which similar phenomena occur. We describe the crystal structure and normal-state properties of the organics, before presenting the experimental evidence for and against exotic superconductivity mediated by antiferromagnetic fluctuations. Finally, three instances of field-induced unconventional superconductivity will be described.

Using a variant of the Corbino geometry in pulsed magnetic fields of up to 60 T, we have made direct measurements of the Hall potential in ␣-(BEDT-TTF) 2 TlHg(SCN) 4 within the quantum Hall regime. This method enables the in-plane components of the resistivity tensor, which are normally very difficult to measure, to be investigated and the nonlinear behavior of the sample's I-V characteristics to be studied. It is found that an increasing probability of magnetic breakdown at higher fields leads to a degradation of the quantum Hall effect. ͓S0163-1829͑99͒50116-1͔ RAPID COMMUNICATIONS R10 420PRB 59 M. M.
