Abstrakt: We report the electronic conduction mechanism in Pr0.67Sr0.13Ag0.20MnO3 synthesized successfully by conventional solid state reaction method. The compound under investigation was subjected by X - Ray diffraction using Rietveld refinement which confirms the single phase nature of the sample. The resistivity behavior indicates the semiconducting behavior and reduction in resistivity on the application of magnetic fields. The electronic nature can further been evaluated by using variable range hopping (VRH) model and small polaron hopping model (SPH) showing that the double exchange interaction increases suppress the band gap and enhances carrier delocalization on the application of magnetic fields.
