چکیده
In this paper, we report transport measurements of interlayer magnetoresistance with field parallel and perpendicular to the current direction in an all organic superconductor b9-~BEDT-TTF!2SF5CH2CF2SO3. For HiI , the isothermal magnetoresistance R(H) at low temperatures (T<Tc) displays a peak effect as a function of field. For H'I , R(H) increases monotonically with increasing field. The results are very analogous to the interlayer magnetoresistance in k-(BEDT-TTF)2X compounds. The observation of the peak effect or negative magnetoresistance in different systems for HiI' plane suggests that it is intrinsic to the layered organic superconductors. For H'I , the large positive magnetoresistance is in a general agreement with a two band model for charge transport. @S0163-1829~99!07405-6#

Anomalous low-temperature and high-field magnetoresistance in the organic superconductor b9-„BEDT-TTF...2SF5CH2CF2SO3
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 کاملThermal activation between Landau levels in the organic superconductor beta(")-(BEDT-TTF)2SF5CH2CF2SO3.
We show that Shubnikov-de Haas oscillations in the interlayer resistivity of the organic superconductor beta(")-(BEDT-TTF)2SF5CH2CF2SO3 become very pronounced in magnetic fields approximately 60 T. The conductivity minima exhibit thermally activated behavior that can be explained simply by the presence of a Landau gap, with the quasi-one-dimensional Fermi surface sheets contributing negligibly ...

In this paper, we report transport measurements of interlayer magnetoresistance with field parallel and perpendicular to the current direction in the organic superconductor k-(BEDT-TTF)2Cu@N(CN)2#Br. For HiJ , the isothermal magnetoresistance R(H) displays a peak effect as a function of field. While the magnetoresistance at small field can be fitted to stacked Josephson junction model, the nega...

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...

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...
