摘要：
Abnormal longitudinal magnetoresistance (LMR) in self-doped silver telluride films at low temperature is investigated. In the Ag-2.1 Te films, we observe the large negative LMR and the multi-peaks in magnetic resistivity rho and 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.
