Directional field-induced metallization of quasi-one-dimensional LiMoO

arXiv:0905.0098 · doi:10.1103/PhysRevLett.102.206602

Abstract

We report a detailed magnetotransport study of the highly anisotropic quasi-one-dimensional oxide LiMoO whose in-chain electrical resistivity diverges below a temperature 25 K. For , a magnetic field applied parallel to the conducting chain induces a large negative magnetoresistance and ultimately, the recovery of a metallic state. We show evidence that this insulator/metal crossover is a consequence of field-induced suppression of a density-wave gap in a highly one-dimensional conductor. At the highest fields studied, there is evidence for the possible emergence of a novel superconducting state with an onset temperature 10 K.
