چکیده
Trie in-plane thermoelectric power (TEP of trie layered orgamc superconductors ~-(BEDT-TTF)2Cu(NCS)2 and ~-(BEDT-TTF)2Cu[N(CN)2]Br bas been studied in trie vicinity of trie superconducting transition under magnetic field. Below trie transition temperature, an anomalous non-monotonic behavior of trie TEP is found in trie ~-(BEDT-TTF)2Cu(NCS)2 sait: instead of a graduai monotonic decrease, trie TEP show~ a prominent sign-change before van-

Thermodynamic Properties of κ-(BEDT-TTF)2X Salts: Electron Correlations and Superconductivity
Heat capacity measurements of κ-(BEDT-TTF)2X (BEDT-TTF: Bis(ethylendithio) tetrathiafulvalene, X: counteranions) which are classified as two-dimensional (2D) dimer-Mott system are reported. At first, we explain structural and electronic features originated from rigid dimerization in donor arrangement in 2D layers. The antiferromagnetic Mott insulating phase located at low-pressure region in the...
متن کاملSpin and Charge Transport in the X-ray Irradiated Quasi-2D Layered Compound: -(BEDT-TTF)2Cu[N(CN)2]Cl
The interplane spin cross relaxation time Tx measured by high frequency ESR in X-ray irradiated κ-(BEDT-TTF)2Cu[N(CN)2]Cl is compared to the interplane resisitivity ρ⊥ and the in-plane resistivity ρ‖ between 50 K and 250 K. The irradiation transforms the semiconductor behavior of the non-irradiated crystal into metallic. Irradiation decreases Tx, ρ⊥ and ρ‖ but the ratio Tx/ρ⊥ and ρ⊥/ρ‖ remain u...
متن کاملSpin fluctuations and the pseudogap in organic superconductors
We show that there are strong similarities in the spin-lattice relaxation of nonmagnetic organic chargetransfer salts and that these similarities can be understood in terms of spin fluctuations. Further, we show that, in all of the -phase organic superconductors for which there is nuclear-magnetic-resonance data, the energy scale for the spin fluctuations coincides with the energy scale for the...
متن کاملStructural disorder and its effect on the superconducting transition temperature in the organic superconductor k-„BEDT-TTF...2Cu†N„CN...2‡Br
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...
متن کاملAspects of unconventional density waves
Recently many people discuss unconventional density waves (i.e. unconventional charge density waves (UCDW) and unconventional spin density waves (USDW)). Unlike in conventional density waves, the quasiparticle spectrum in these systems is gapless. Also these systems remain metallic. Indeed it appears that there are many candidates for UDW. The low temperature phase of α-(BEDT-TTF)2KHg(SCN)4, th...
