[en] La_0.85Ag_0.15Mn_1-yAl_yO₃ compounds were prepared for y = 0 to 0.20 by solid-state route. X-ray diffraction (XRD) patterns were recorded at room temperature and could be refined by using R3-barc space group by employing Rietveld techniques. Temperature variations of ac susceptibility down to 30 K were measured at an ac field amplitude of 6 Oe. All the samples exhibit paramagnetic to ferromagnetic transition and the transition temperature decreases at the rate of 1.6 K/Al%. Temperature variations of dc electrical resistivity and magneto-resistivity at 10 kOe were measured down to 25 K for all the above samples. Metal-insulator (M-I) transition has been observed for all the samples with transition temperature (T_p) ranging from 285 to 213 K. Resistivity in the metallic region could be explained on the basis of combination of electron-electron and electron-magnon scattering
