The effect of hydrostatic pressure up to 8.5 GPa on the transport characteristics of granular ceramic manganite La0.8Ag0.1MnO3 near the temperature corresponding to the magnetoresistance peak has been studied. The electrical resistivity has been measured in the temperature range of 275–320 K at pressures P = 0, 0.44, 2.32, 3.81, and 4.84 GPa. The temperature of the transition from the metallic to semiconductor type of conductivity is a monotonically increasing function of the applied pressure with a slope of 4.54 K/GPa. At 296 K, the linear logarithmic plot of the pressure dependence of the resistivity exhibits an anomaly in the form of a kink at 3.85 GPa. It has been shown that the observed transition with a change in the slope in the logarithmic plot of the pressure dependence of the resistivity is due to the existence of two scattering processes: intragranular and near-boundary ones. Near the transition point, both scattering processes make comparable contributions to the resistivity. For pressures P < 3.85 GPa, the contribution to the resistivity from scattering in the boundary layers of grains dominates, whereas the contribution from the homogeneous material within the grains is dominant in the high-pressure range.
