Interlayer resistance is reported in a layered organic superconductor β"−(BEDT−TTF)2SF5CH2CF2SO3 with Tc ≈ 5 K. At 0.7 K in parallel magnetic fields, the interlayer resistance has nonzero values in a wide field region from 2 T to the upper critica...

Superconductivity is one of the most intriguing topics in solid state physics. Generally, the superconducting Cooper pairs are broken by the Zeeman effect, which gives the so-called Pauli paramagnetic limit H_Pauli. However, when the superconducti...

Resistance and magnetic torque measurements are reported in a layered organic superconductor, β"-(BEDT-TTF)4[(H3O)Ga(C2O4)3]C6H5NO2 with Tc=4.8 K, where BEDT-TTF stands for bis(ethylenedithio)tetrathiafulvalene. Because of the large anion between ...

Resistance measurements have been performed to investigate the dimensionality and the in-plane anisotropy of the upper critical field (Hc2) for β-(BDA-TTP)2SbF6in fields H up to 15 T and at temperatures T from 1.5 to 7.5 K, where BDA-TTP stands fo...

We investigate the phonon density of states in nonstoichiometric palladium hydrides PdH x , in order to clarify the contribution of lattice vibrations to superconductivity. We employ the Burger-MacLachlan model, which considers a one-dimensional t...
