摘要
The magnetoresistance and magnetization have been measured in (DMET-TSeF)(2)X (X=AuI2, Au(Br)(2), AuCI2, Au(CN)(2) and I-3.) family. AH of them have quasi one-dimensional Fermi surfaces at room temperature. It has been shown that two (AuI2, and I-3) of them show superconductivity. We have also found three salts which show field induced spin density wave state, two at ambient pressure, and one under pressure. Another investigation is that I-3 salt is superconducting, but does not show FI-SDW nor Shubnikov-de Haas oscillation in spite of the comparatively large magnetoresistance.
