Solution combustion synthesis of (La, K) FeO3 orthoferrite ceramics: structural and magnetic property studies

Polycrystalline La 1− x K x FeO 3 ceramic oxides were synthesized by a solution combustion process using glycine as a fuel. The synthesized ceramic powders were characterized for structural features applying characterization techniques such as powder X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and magnetic and optical property studies applying characterization techniques such as SQUID magnetometer and diffuse reflectance (DR). The changes in magnetic properties are correlated to changes in structural features resulting from Rietveld structural refinement.
