Abstract

The comparative studies of pure and different doping materials of α-XFe₂O₃ (X = Co, Mn, Ni and Zn) nanoparticles in Structural, Morphological, Optical, and magnetic behavior were analyzed in this article. The synthesis of α-XFe₂O₃ nanoparticles through the Sol-gel method for magnetic properties with various doping materials such as Co, Mn, Ni, and Zn. The structural, morphological, optical, and magnetic properties were carefully examined, revealing enhanced characteristics. XRD studies confirmed the successful incorporation of dopants into the crystal structure of α-Fe₂O₃, while Morphological analysis through SEM images indicated superparamagnetic properties in Co and Zn doped samples, and ferrite behavior in Mn and Ni doped samples. UV Spectra analysis showed optical transitional changes related to magnetic behavior, and the dielectric effect was attributed to the presence of multiple domains within the sample. The study effectively demonstrated the unique magnetic properties of pure and α-XFe₂O₃ nanoparticles, highlighting the importance of different doping materials in influencing their characteristics.

结合氧化铁探索不同的掺杂材料，并分析其特性和磁性能

本文分析了纯α-XFe2O3（X = Co、Mn、Ni 和 Zn）纳米粒子和不同掺杂材料在结构、形态、光学和磁学行为方面的比较研究。通过溶胶-凝胶法合成了α-XFe2O3纳米粒子，并掺杂了不同的磁性材料，如Co、Mn、Ni和Zn。对这些纳米粒子的结构、形态、光学和磁学特性进行了仔细研究，结果表明它们具有更强的特性。XRD 研究证实掺杂剂成功地掺入了 α-Fe2O3 的晶体结构中，而通过 SEM 图像进行的形态分析表明，掺杂 Co 和 Zn 的样品具有超顺磁性，而掺杂 Mn 和 Ni 的样品则具有铁氧体特性。紫外光谱分析显示了与磁性行为相关的光学过渡变化，而介电效应则归因于样品中存在多个畴。该研究有效地证明了纯纳米颗粒和 α-XFe2O3 纳米颗粒的独特磁特性，突出了不同掺杂材料对其特性影响的重要性。

期刊介绍： Chemical Physics publishes experimental and theoretical papers on all aspects of chemical physics. In this journal, experiments are related to theory, and in turn theoretical papers are related to present or future experiments. Subjects covered include: spectroscopy and molecular structure, interacting systems, relaxation phenomena, biological systems, materials, fundamental problems in molecular reactivity, molecular quantum theory and statistical mechanics. Computational chemistry studies of routine character are not appropriate for this journal.
