Pressure dependence of superconductivity in the pseudo-one-dimensional compound Tl₂Mo₆Se₆

Abstract

Measurements of the temperature and pressure dependences of the resistivity of the pseudo-one-dimensional ternary compound Tl2Mo6Se6 are presented. We find that the conductivity parallel to the highly conducting c-axis is enhanced by pressure and the superconducting transition temperature Tc is suppressed by pressure at a rate θ{symbol}Tc θ{symbol}P=-7.6×10-5 kbar-1. These results are discussed in relation to the current models of transport in one-dimensional conductors. © 1983.
