Abstract

In this study, Mn_0.15Mg_0.15Cu_0.2Zn_0.5Fe_2−xTi_xO₄ (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 Mn_0.15Mg_0.15Cu_0.2Zn_0.5Fe_2−xTi_xO₄ nanoparticles and highlighted their potential for various applications, particularly in the fields of magnetism and optoelectronics.

钛替代物对溶胶-凝胶法制备的锰镁铜锌铁氧体的结构、光学和磁学特性的影响

本研究采用溶胶-凝胶自燃烧法合成了 Mn0.15Mg0.15Cu0.2Zn0.5Fe2-xTixO4 (x = 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6) 纳米粒子，并研究了它们的结构、磁性和光学特性。研究采用了多种表征技术，包括 X 射线粉末衍射 (XRD)、傅立叶变换红外光谱 (FTIR)、拉曼光谱和磁化测量。对 XRD 数据的里特维尔德细化证实，样品呈现出立方尖晶石结构，空间群为 Fd \(\overline{3 }\)m 。傅立叶变换红外光谱和拉曼光谱的结果进一步证实了这一结论。有趣的是，样品的粒度随着四价 Ti4+ 取代量的增加而增大。与此相反，晶粒尺寸和晶格参数却减小了。对样品的光学特性进行研究后发现，样品 x = 0.3 的能隙值最大。此外，饱和磁化率从样品 x = 0.0 的 41.47 emu/g 降至样品 x = 0.6 的 7.36 emu/g。总之，这项综合研究证明了 Mn0.15Mg0.15Cu0.2Zn0.5Fe2-xTixO4 纳米粒子的可调特性，并突出了它们在各种应用领域的潜力，尤其是在磁学和光电子学领域。

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.
