متن کاملElectrical transport in the organic superconductor /1-(BEDT -TTFhAuI2 [with BEDT-TTF bis(ethylenedithio)tetrathiafulvalene]: Influence of x-ray-induced defects on the normal phase and superconducting ground state
We have measured the in-plane and out-of-plane resistivities of the organic superconductor p-(BEDTTTF)zAuIz with disorder introduced by x-ray irradiation. [Here BEDT-TTF is bis(ethylenedithio)tetrathiafulvalene]. For defect concentrations less than 0.15% per mole, Matthiessen's rule is obeyed at all temperatures and a T Z term in the resistivity is found in the temperature region between 5 and ...

We report direct observations of anomalous magnetic-field and temperature dependences of the Shubnikov–de Haas oscillations in the organic superconductor b9-(BEDT-TTF)2SF5CH2CF2SO3. Unlike other BEDT-TTF based organic superconductors, a nonmetallic temperature dependence of the background magnetoresistance is clearly observed. It is speculated that the nonmetallic behavior may arise from a part...
متن کاملDependence of the superconducting transition temperature of organic molecular crystals on intrinsically nonmagnetic disorder: A signature of either unconventional superconductivity or the atypical formation of magnetic moments
We give a theoretical analysis of published experimental studies of the effects of impurities and disorder on the superconducting transition temperature Tc of the organic molecular crystals k-(BEDT-TTF)2X „where X5Cu@N(CN)2#Br and Cu(NCS)2 and BEDT-TTF is bis~ethylenedithio!tetrathiafulvalene... and b-(BEDT-TTF)2X ~for X5I3 and IBr2). The Abrikosov-Gorkov ~AG! formula describes the suppression ...

In this paper, we report direct evidence of a structural transition in the organic superconductor k-~BEDT-TTF!2Cu@N~CN!2#Br near 80 K and the effect of disorder on the superconducting transition temperature. By cooling the sample from above 80 K, the interlayer magnetoresistance displays a bumplike feature, which increases sharply with increasing cooling rate. The rapidly cooled sample has a mu...
