Abstract

Four probe electrical resistivity measurements between 1.5 and 300 K were made on single crystals of the violet-red bronze Na_0.9Mo₆O₁₇ grown by a temperature gradient flux technique. The temperature variation of the resistivity shows metallic conductivity and highly anisotropic behavior similar to K_0.9Mo₆O₁₇ and Li_0.9Mo₆O₁₇. The room-temperature resistivity, measured in the direction parallel to the plate axis, is 3.0 × 10^-3 Ω cm and perpendicular to that axis it is 0.21 Ω cm. A transition observed at ∼88 K is possibly related to the onset of a charge density wave. The temperature variation of the susceptibility show Pauli paramagnetic behavior at high temperature, and highly anomalous behavior in the vicinity of the transition at low temperatures.
