Magnetotransport Properties of Quasi-one Dimensional Organic and Inorganic Conductors
I will present our comparative study of the magnetotransport properties of organic conductors (TMTCF)2X (C= Se, S). Their phase diagram spanning from more anisotropic C = S to C = Se series shows the increasing interchain coupling that leads to the crossing-over of the dimensionality. Our results of the conductivity anisotropy, Hall effect and magnetoresistance enabled us to gain information about the spin density wave ground state at low temperature, Fermi liquid or Luttinger liquid behavior in the normal phase at high temperatures, possible dimensional crossover and phase transitions. The results are discussed in the framework of the existing theoretical models. The evidence that the 1D Luttinger liquid features appear in the transport properties at high temperatures in C=S series will be addressed. I will also present our results of the Hall effect measurements of quasi-one-dimensional cuprates Sr14-xCaxCu24O41 ( 0 ≤ x ≤ 11.5) that have been conducted in order to determine the number of carriers participating in dc transport, and its relationship with doping. Namely, a fair number of investigations were dedicated to the distribution of holes in the parent system at room temperature with contradictory results ; the reason for that has not been clarified.
