Rare Earth Metal Samarium Doped Ferrite and Its Structural, Morphological, Magnetic, and Optical Studies for Biomedical Applications

AbstractThe x-ray diffraction analysis manifested the single phases of Fe2O3, SmFeO3, and v SmFeO3 synthesized via sol-gel route. The Fe2O3, SmFeO3, and v SmFeO3 were hexagonal, orthorhombic, and cubic, respectively. The Debye-Scherer formula was used to calculate the average crystallite size of Fe2O3 (85.54 nm), SmFeO3 (67.65 nm), and v SmFeO3 (49.58 nm). The FESEM reveals near-spherical morphology with average particle sizes of 173, 114, and 161 nm, respectively. VSM analysis revealed the enhanced magnetic behavior of SmFeO3 and v SmFeO3 compared to Fe2O3. Antimicrobial activity against both E. coli and S. aureus bacteria justifies the biomedical application.Keywords: Antimicrobialferritesmagnetic nanoparticlessamariumrare earth material Disclosure StatementNo potential conflict of interest was reported by the author(s).AcknowledgmentsThe authors are grateful to the Centre for Interdisciplinary Research (CIR), MNNIT Allahabad, Prayagraj, and IIT Kanpur, for the characterization of the materials.Additional informationFundingThis work was supported by the Ministry of Education, Govt. of India, by giving an M.
