Description
La0.85Ag0.15Mn1-yAlyO3 compounds were prepared for y = 0, 0.05 and 0.10 by solid-state route. XRD patterns show that all the samples are in single phase form. Temperature variations of ac susceptibility down to 25 K were measured at an ac field amplitude of 6Oe. All the above samples exhibit paramagnetic to ferromagnetic transitions with a decrease in ferromagnetic transition temperature (Tc) with an increase in Al doping. Temperature variation of DC electrical resistivity was measured down to 25 K for all the samples. Metal-insulator (M-I) transition has been observed in all the samples with maximum transition temperature (Tp) at 285K for y = 0 sample. (author)
