Theoretical and experimental investigation of NiFe2O4 and CaMnO3 nanoparticles to study their structural, magnetic, and polarization properties for energy-related applications (opens in new tab)

This work presents a comparative theoretical and experimental investigation of spinel nickel ferrite (NiFe2O4) and perovskite calcium canganite (CaMnO3) nanoparticles synthesized via the sol-gel method. NiFe2O4 samples were calcined at temperatures ranging from 400 to 1000 °C, and the CaMnO3 samples were calcined at temperatures ranging from 300 to 600 °C. X-ray diffraction (XRD) confirmed the formation of both materials, and the highest peak was observed at 2θ = 35.816° for NiFe2O4 and 2θ = ...
