Influence of Ce3+ Substitution on Magnetic Properties and Antibacterial Activity of
Manganese Ferrite Nanoparticles Synthesized by Coprecipitation Method

Rare earth element cerium incorporated MnFe2O4 nanoparticles were synthesized by using a
co-precipitation method. Phase signature, vibrational analysis, morphology, element composition,
magnetometry, surface analysis, medicated analysis were studied by XRD, FTIR, FE-SEM, EDAX,
VSM, XPS and antibacterial activity. X-ray diffraction (XRD) reveals a cubic structure and obtained
crystallite size and lattice constant. Fourier transform infrared spectroscopy (FTIR) studies were
confirmed spinel structure ferrite. Vibrating sample magnetometer (VSM) revealed that the magnetic
interaction of materials and obtained saturation magnetization, remnant magnetization and coercivity,
which were impressed by their magnetic properties by Ce3+ incorporated MnFe2O4. Field emission
scanning electron microscope (FE-SEM) observed clear lattice size and magnetic domain nature.
X-ray photoelectron spectroscopy (XPS) confirmed cerium (Ce3+) ions in the all doped materials and
identified the chemical state of ions in the ferrite composite. Antioxidant effects were observed against
Gram-positive and Gram-negative bacteria ferrite nanoparticles.
