Electron Density Distribution in the Organic Superconductor (TMTSF)2AsF6.

چکیده
Excellent crystals of (TMTSF)(2)AsF(6) (TMTSF, tetramethyltetraselenafulvalene) were employed to obtain x-ray diffraction data for a determination of the electron density distribution in this organic superconductor. Electron density was observed between molecules in a stack of donors of an organic metal and between certain interstack selenium atoms of these donors.

Two decades ago the epoch making discovery of high Tc cuprate superconductivity by Bednorz and Müller shocked the world’s superconductivity community. However, already in 1979 and 1980, the first heavy fermion superconductor CeCu2Si2 and organic superconductor (TMTSF)2PF6 have been discovered respectively. Also we know now that all these superconductors are unconventional and nodal. Further t...
متن کاملTransient voltage oscillation, narrow-band-noise and non-linear conductivity in SDW : (TMTSF)2AsF6
Transient voltage oscillation was observed in the spin-density wave phase of (TMTSF)2AsFs. Its frequency is proportional to the non-ohmic current. In high electric field, current-field relation becomes irregular and transient oscillation diminishes. The bistability of the density-wave conductivity proposed by Littlewood is likely to be realized.
متن کاملInsulating, conducting and superconducting states of (TMTSF)2AsF6 under pressure and magnetic field
2014 We report resistivity measurements along the high conductivity axis of (TMTSF)2AsF6 for various hydrostatic pressures up to 12 kbar, and for transverse magnetic fields of up to 70 kOe, in the temperature range 0.1 K-300 K. We derive a phase diagram which shows a « triple » point near Tc = 1.22 K and Pc = 10.5 kbar, and a reentrant behaviour of the superconducting state inside the semicondu...
متن کاملCoexistence of Superconductivity and Spin Density Wave orderings in the organic superconductor (TMTSF)2PF6
The phase diagram of the organic superconductor (TMTSF)2PF6 has been revisited using transport measurements with an improved control of the applied pressure. We have found a 0.8 kbar wide pressure domain below the critical point (9.43 kbar, 1.2 K) for the stabilisation of the superconducting ground state featuring a coexistence regime between spin density wave (SDW) and superconductivity (SC). ...
متن کاملIrradiation effects on the plasma edge of organic conductors based on TMTSF
2014 The reflectance of 17 irradiated single crystals of (TMTSF)2PF6, (TMTSF)2AsF6 and (TMTSF) (DMTCNQ) have been measured at room temperature in the frequency range 5 000 to 12 000 cm-1 corresponding to the metallic plasma edge. The reflectance curves have been satisfactorily fitted to a Drude model in order to measure the influence of radiation induced defects on the plasma frequency and the ...
