Thermal 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 ...
متن کاملSome electronic properties of the organic superconductor - (BEDT-TTF )2I3
2014 We report some results of magnetoresistance, magnetic susceptibility and magnetic anisotropy measurements on single crystals of the two dimensional organic superconductor 03B2L-(BEDT-TTF)2I3 from 4.2 to 300 K. From the c* magnetoresistivity we deduce a value of 0.5 meV for the tight binding transfer integral tc, and show that there is significant conductivity anisotropy (a factor 5) in the...

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 resul...
متن کاملLow-temperature microwave surface impedance of the conventional organic superconductor kappa -(BEDT-TTF)2Cu(NCS)2.
We have performed measurements of the microwave surface impedance Zs = Rs + iXs of the organic superconductor 1\;-(BEDT-TTF)zCu(NCS)z down to T = 0.8 K. The reactance Xs, and therefore the penetration depth A, exhibits no temperature dependence for T «Te • This result is in full agreement with calculations of the BCS ground state and gives no indication of unconventional pairing. Furthermore, w...
متن کاملAnomalous 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...
