Effect of Ti Substitution on the Structural, Optical, and Magnetic Properties of Mn-Mg-Cu-Zn Ferrite Prepared by the Sol–Gel Route
In this study, Mn0.15Mg0.15Cu0.2Zn0.5Fe2−xTixO4 (x = 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6) nanoparticles were synthesized using the sol–gel auto-combustion method, and their structural, magnetic, and optical properties were investigated. Various characterization techniques were employed, including X-ray powder diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, and magnetization measurements. The Rietveld refinement of XRD data confirmed that the samples exhibited a cubic spinel structure with space group Fd\(\overline{3 }\)m. This conclusion was further supported by the results of FTIR and Raman spectroscopy. Interestingly, the particle size of the samples increased with an increase in the tetravalent Ti4+ substitution. In contrast, the crystallite size and lattice parameter decreased. The optical properties of the samples were studied, revealing a maximum energy gap value in sample x = 0.3. Furthermore, the saturation magnetization decreased from 41.47 emu/g in sample x = 0.0 to 7.36 emu/g in sample x = 0.6. Overall, this comprehensive investigation demonstrated the tunable properties of Mn0.15Mg0.15Cu0.2Zn0.5Fe2−xTixO4 nanoparticles and highlighted their potential for various applications, particularly in the fields of magnetism and optoelectronics.
期刊介绍：
The Journal of Electronic Materials (JEM) reports monthly on the science and technology of electronic materials, while examining new applications for semiconductors, magnetic alloys, dielectrics, nanoscale materials, and photonic materials. The journal welcomes articles on methods for preparing and evaluating the chemical, physical, electronic, and optical properties of these materials. Specific areas of interest are materials for state-of-the-art transistors, nanotechnology, electronic packaging, detectors, emitters, metallization, superconductivity, and energy applications.
Review papers on current topics enable individuals in the field of electronics to keep abreast of activities in areas peripheral to their own. JEM also selects papers from conferences such as the Electronic Materials Conference, the U.S. Workshop on the Physics and Chemistry of II-VI Materials, and the International Conference on Thermoelectrics. It benefits both specialists and non-specialists in the electronic materials field.
A journal of The Minerals, Metals & Materials Society.
