AbstractThe magnetic and electron transport properties of rhombohedral LixVyO2 (x=0.8 and y=0.8) are studied. The dc susceptibility of LixVyO2 can be well fitted to the modified Curie-Weiss law, which verified the paramagnetic ground state. The magnetic hysteresis and ac susceptibility also confirm this paramagnetism. The LixVyO2 exhibits semiconducting behavior, which is explained by thermal activated process at high temperature and variable-range hopping mechanism at low temperature. Anderson localization plays an important role in both the electron transport behavior and the magnetic behavior due to the site disorder between the Li+ ion and V4+ ion. © 2008 Elsevier B.V.
