چکیده

Recently, bulk superconductivity at ambient pressure in polycrystalline pressed samples of an organic metal a,-(BEDT-TTF),I, was observed."' This is a remarkable fact because this finding shows that organic superconductors can in principle be used for the production of electronic devices, such as squids, and might even be suitable for the preparation of superconducting cables similar to the high temperature superconductors of the copper oxides. The polycrystalline pressed samples of a,-(BEDT-TTF),I, were prepared from pulverized single crystals of a-(BEDTTTF),13 and the pressed samples had to be anealed at 75 "C

STATIC AND ESR SUSCEPTIBILITIES OF THE AMBIENT PRESSURE SUPERCONDUCTORS p AND at-( BEDT-TTF)213 AND (BEDT-TTF)2Cu( SCN)2

Whereas the static spin-susceptibility x5(T) of b and at-(BEDT-TTF)& at 5.7 tesla increases in a slow monotonic manner with temperature, xS(T) for the organic superconductor (BEDT-TTF)$Zu(SCN)2 displays a markedly structured temperature dependence. This gives evidence for two or more phase transitions in the metallic phase at temperatures near 100 K and 50 K, in addition to the onset of superco...

Transport Phenomena in Multilayered Massless Dirac Fermion System α-(BEDT-TTF)2I3

A zero-gap state with a Dirac cone type energy dispersion was discovered in an organic conductor α-(BEDT-TTF)2I3 under high hydrostatic pressures. This is the first two-dimensional (2D) zero-gap state discovered in bulk crystals with a layered structure. In contrast to the case of graphene, the Dirac cone in this system is highly anisotropic. The present system, therefore, provides a new type o...

Theory of Dirac Electrons in Organic Conductors

The dynamical property of electrons with the tilted Dirac cone was examined using the tilted Weyl equation. The polarization function exhibits cusps and nonmonotonic structures by varying both the frequency and the momentum. A pair of tilted Dirac cones exhibits a new plasmon for the intermediate magnitude of momentum owing to the combined effects of two tilted cones. Dirac electrons with the z...

Superconductivity, incoherence and Anderson localization in the crystalline organic conductor (BEDT-TTF)3Cl2·2H2O at high pressures

The conducting properties of the pressure-induced, layered organic superconductor (BEDT-TTF)3Cl2·2H2O have been studied at 13.5 and 14.0 kbar using low temperatures, high magnetic fields and two-axis rotation. An upper critical field that is significantly larger than that expected from the Pauli paramagnetic limit is observed when the field is applied parallel to the conducting layers. The angl...
