Synthesis, characterization, and property studies of (La, Ag) FeO3 (0.0 ≤ x ≤ 0.3) perovskites

Applying a solution - based combustion process, Ag-doped LaFeO3 orthoferrites were synthesized. The samples were characterized by multiple techniques to establish structure - property relationships. Specifically, for structural characterization, powder X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), Fourier transmission infrared spectroscopy (MR), Thermo-gravimetric analysis (TGA), and X-ray photoelectron microscopy (XPS) were carried out. For properties, squid magnetometer measurements (for magnetic properties), titrations (for chemical analysis), and diffuse reflectance (for optical band gap properties) measurements were carried out to elucidate structure-property relationship.
