A new steady-state method is proposed to simultaneously measure the heat capacity and internal relaxation time using superimposed constant and square-wave power. This method is appropriate for small sample systems with low thermal conductance. The ac

We measured the specific heat c p ( T ) of single crystals of quasi-one-dimensional conductors K 0.3 MoO 3 and (TMTTF) 2 AsF 6 by differential thermal analysis (DTA) method. In K 0.3 MoO 3 , a clear discontinuous change Δ c p 0 ∼1.2 J/mol/K was de

In the charge ordering (CO) state of the quasi-one dimensional conductors (TMTTF) 2 SbF 6 , we measured the current-voltage relations by the pulse current method at ambient pressure. From the measurement, we found that the conductivity is constant at

By method of dielectric spectroscopy we have obtained experimental data concerning the 4k F charge density wave (CDW) associated with the charge ordering (CO) state of Wigner type in (TMTTF) 2 X conductors. A divergence of the relaxation time was fou

We measured the electrical conductance along the adirection σa of (TMTTF)2SbF6 under anisotropic external pressure PEc which is parallel to the c *-direction. It is expected that PEc achieves the uniaxial strain along the c *-direction to the sample

Zero and longitudinal field muon-spin-relaxation ( μ SR ) experiments were carried out in organic spin-Peierls material, TMTTF 2 PF 6 . An enhancement of muon spin depolarization rate is observed at the temperature somewhat lower than spin-Peierls t

We measured the conductivity along the a-direction σ a ( T ) of the quasi one-dimensional organic conductor (TMTTF)2SbF6 under several anisotropic pressures of uniaxial strains which are parallel and perpendicular to the a-direction. The uniaxial st

Quasi-one-dimensional organic conductors (TMTTF)2X [X 1⁄4 Br, PF6, AsF6, SbF6, . . .] show a large variety of phase transitions. The electric system is expected to have a halffilled band because the unit cell is composed of two dimerized TMTTF mole
