Measurements of the London penetration depth, λ(T), are reported for crystals of superconducting κ-(ET) 2 Cu[N(CN),]Br (T C = 11.6 K) and β-(ET) 2 -SF 5 CH 2 CF 2 SO 3 (T C = 5.2 K) at temperatures down to 0.35 K. For K-(ET)2 Cu[N(CN)2]Br the supe

κ-(BEDT-TTF) 2 Cu(NCS) 2 is one of the best characterized organic superconductors. The resemblance of its pressure-temperature phase diagram to that of the carrier-density-temperature phase diagram in cuprate superconductors has frequently been take

We determined the pressure dependence of the superconducting transition temperature, Tc, of the organic superconductor κ-(BEDT-TTF)2Cu(SCN)2 for three different isotopic compositions using helium as a pressure medium. These measurements demonstrated

High-resolution measurements of the coefficient of thermal expansion, α ( T ), on the superconductors κ-(BEDT-TTF) 2 X with X=Cu[N(CN) 2 ]Br and Cu(NCS) 2 reveal distinct anomalies at T ∗ around 40 K—the same temperature where the opening of a

The infrared reflectivity of the organic conductor α-(BEDT-TTF) 2 KHg(SCN) 4 has been measured as a function of polarization and temperature. The optical conductivity spectra obtained by the Kramers–Kronig analysis show different electronic contri

Three 2 : 1 salts of the organic donor molecule bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF or ET) with trifluoromethylsulfonyl-based anions N(SO2CF3)2−, CH(SO2CF3)2− and C(SO2CF3)3− were prepared by electrocrystallization. These salts were

The interlayer transfer integrals of various organic superconductors have been deduced using high-magnetic-field techniques. The measurements demonstrate the inappropriateness of criteria used to denote incoherent interlayer transport.

We present the room-temperature Raman spectra of both the protonated and deuterated forms of kappa-(BEDT-TTF)2Cu[N(CN)2]Br, kappa-(BEDT-TTF)2Cu(NCS)2 and beta-(BEDT-TTF)2I3. Along with data for the neutral BEDT-TTF molecule these spectra are used to

The organic superconductors program at Argonne National Laboratory was started by Jack M. Williams in 1981. Initial studies centered around structural effects in the TMTSF salts. Since 1984, the major emphasis has been on salts of the electron donor

Raman and infrared spectra of several organic superconductors are presented, showing some unusual behaviours of a sharp line at 890 cm −1 in both spectra. These include a frequency shift below T c , a positive deuterium isotope shift, frequency sof
