Abnormal longitudinal magnetoresistance (LMR) in self-doped silver telluride films at low temperature is investigated. In the Ag2.1Te films, we observe the large negative LMR and the multipeaks in magnetic resistivity ρand LMR that strongly depend on doping concentration and temperature. The abnormal MR behavior, which might result from the complex structure and texture of the films, is explained by means of Toyozawa model.
