Abstract

Nanocrystalline Ni and Zn ion-doped Co-ferrites with the chemical formula M_0.2Co_0.8Fe₂O₄ (M = Ni/Zn) were synthesized using the citrate-gel method. X-ray diffraction (XRD) studies confirmed the phase and crystalline nature of the samples. The addition of Ni and Zn ions to CoFe₂O₄ slightly modifies its structural and magnetic properties. The crystallite size, experimental density, cation distribution from intensity calculations, and structural parameters, including bond lengths and angles, were studied using the XRD data. FTIR studies also supported the structure and proposed cation distribution analysis. FESEM carried out morphological studies, and it was observed that both the samples exhibited spherical particles. In addition, EDAX studies confirmed the stoichiometry of both samples. Magnetization studies were carried out by vibrating sample magnetometer (VSM); it was observed that the Zn-substituted sample showed a lower saturation magnetization value (60 emu/g) compared with the Ni substituted (73.6 emu/g) sample. Antimicrobial and cytotoxicity studies have revealed that these samples are well suited for magnetic hyperthermia and biomedical applications.
