摘要
Single crystals of (PO2)(4)(WO3)(2m) (m=5) have been studied by transport (resistivity, magnetoresistance and thermopower) measurements. They reveal a metallic behavior with anomalies in the resistivty vs temperature showing an elbow at T-1=100K and a weak hump around T-2=30K. Giant magnetoresistance appears below T-2. Both anomalies can also be observed as kinks in the thermopower behavior. They could be associated with Peierls instabilities and charge density waves.
