An NMR study of the organic superconductor : (TMTSF)2ClO4
نویسندگان
چکیده
2014 We report 1H and 77Se-NMR data on oriented single crystals which establish the magnetic character of the semi-metallic ground state stabilized under high magnetic field in (TMTSF)2ClO4. A similar magnetic state can be stabilized at low temperature in the absence of magnetic field by non-magnetic molecular disorder. At low temperature the spin-lattice relaxation rate does not follow the Korringa law. A large enhancement of the relaxation rate occurring below ~ 12 K may be related to the onset of the SDW instability (whenever it exists) or to the development of short range superconducting fluctuations.

High resolution 13C NMR investigation in the organic conductor : (TMTSF)2ClO4
2014 We report the results of 13C NMR magic angle spinning experiments performed on the TMTSF molecule (in solution and in the solid state) and in the organic conductor (TMTSF)2ClO4. This investigation (Knight-shift, T1 and T103C1) has allowed to resolve all individual sites of the organic molecule. Strong and widely distributed enhancements of the relaxation rate of the nuclear spin on differe...
متن کاملPeriodic-orbit resonance in the quasi-one-dimensional organic superconductor „TMTSF...2ClO4
We report the observation of periodic-orbit resonance POR in a metal possessing pure quasi-onedimensional Q1D Fermiology—namely, the organic linear-chain compound TMTSF 2ClO4, whose Fermi surface consists of a pair of weakly warped sheets. The POR phenomenon is related to weak interchain coupling, which allows electrons constrained on open trajectories to acquire small transverse velocities. Th...
متن کاملImpurity controlled Superconductivity/Spin Density Wave interplay in the organic superconductor : (TMTSF)_2ClO_4
– The study of the anion ordered (TMTSF )2ClO4(1−x)ReO4x solid solution in the limit of a low ReO− 4 substitution level (0 ≤ x ≤ 17%) has revealed a new and interesting phase diagram. Superconductivity is drastically suppressed as the effect of ReO− 4 non magnetic point defects increases following the digamma behaviour for usual superconductors in the presence of paramagnetic impurities. Then, ...
متن کاملObservation of a Non-Magnetic Impurity Effect in the Organic Superconductor (TMTSF)2ClO4
We report a non-magnetic impurity effect on the superconductivity observed in (TMTSF)2ClO4. By varying the sample cooling rate in the vicinity of an anion ordering transition at TAO = 24 K, we can systematically control the amount of disorder in the sample. We then use dc transport and microwave periodic orbit resonance measurements (closely related to cyclotron resonance) to determine the crit...
متن کاملAnomalous in-plane anisotropy of the onset of superconductivity in (TMTSF)2ClO4.
We report the magnetic-field amplitude and field-angle dependence of the superconducting onset temperature Tconset of the organic superconductor (TMTSF)2ClO4 in magnetic fields H accurately aligned to the conductive ab' plane. We revealed that the rapid increase of the onset fields at low temperatures occurs both for H || b' and H || a, irrespective of the carrier confinement. Moreover, in the ...
