Abstract
Resistivity measurements of TiTe2 have been made. Above 10 K, a typical metallic behavior has been observed, while at low temperatures an increase of resistivity with a log T dependence has been found. From measurements of magnetoresistance, this anomaly has been concluded to be due to not the Kondo effect but the two-dimensional Anderson localization in the weakly localized regime. Negative magnetoresistance observed for J┴H//c-axis is proportional to in low fields and to log H in intermediate fields and saturates about 40 kOe. This field dependence is in good agreement with Hikami et al.'s theory based on the two-dimensional localization. Moreover, TiTe2 seems to be a new system, where two carriers (three-dimensional and two-dimensional) exist and the two-dimen-sional carriers are considered to be localized at low temperatures.
