Abstract

In this paper, we investigate the transport properties and magnetoresistance effect of La_0.8Ca_0.13Ag_0.07MnO₃ perovskite manganite synthesized by sol-gel method. The XRD pattern of the sample shows a rhombohedral perovskite structure with space group R3c. The EDX analysis confirms that the sample contains all expected chemical elements without any additional impurity. The temperature dependence of electrical resistivity was measured using a cryogenic magnetometer. The results show a metal-insulator transition temperature (T_M-I ) at 280 K. The resistivity of the sample increases with an increase of temperature below T_M-I . Theoretical analyses of the temperature dependence of resistivity suggest that the resistivity due to electron-electron scattering is predominant below T_I-M. The resistivity of the sample decreases when applied magnetic field 1 T at a temperature range of 10 K to 300 K. The magnetoresistance of La_0.8Ca_0.13Ag_0.07MnO₃ emanates from spin-polarized tunneling process at the grain boundary.
