Manganite containing La is a promising perovskite material as it has wide range of applications. In this piece of work, nanoparticles of La1−xAgxMnO3 samples (0.00 ≤ x ≤ 0.09) were synthesized using wet chemical method. The samples were characterized by thermal gravimetric analysis (TGA), field emission scanning electron microscopy (FE-SEM), differential thermal analysis (DTA), high-resolution transmission electron microscopy (HR-TEM), X-ray diffraction (XRD), infrared spectroscopic (FT-IR), and differential scanning calorimetry (DSC). The XRD study showed that all samples adopted the rhombohedral hexagonal structure with a space group of Rc. The HR-TEM/FE-SEM images showed that the perovskite structure were suc cessfully obtained. Investigation of the magnetic properties was conducted in a wide range of temperature to confirm the ferromagnetic-paramagnetic (FM-PM) presence around Curie temperature (Tc ≈ 270 K). The shift of the Curie point to larger values was clearly observed for the samples by increasing the silver contents.
