Abstract

In the present work, CuEu_0.01Fe_1.99O₄ and CuEu_0.01Sc_0.01Fe_1.98O₄ nanoparticles were prepared by self-propagating high-temperature synthesis method for reporting the structural, microstructural, and magnetic properties of prepared samples. X-ray diffraction (XRD) patterns confirmed the spinel cubic structure with space group Fd3m. An average crystallite size was found in the range of 20–40 nm. Scanning electron microscopy (SEM) investigations indicated the porous nature and particles agglomeration. The elemental composition of samples was studied by using energy-dispersive X-ray spectroscopy (EDS). The magnetic hysteresis loop revealed the soft ferromagnetic nature. Magnetic parameters such as saturation magnetization, coercivity, and remanence magnetization decrease with an increase in Eu³⁺ and Sc³⁺ concentration.

自传播高温合成法制备铕钪掺杂1mol % CuFe2O4的合成及结构、微观结构和磁性能研究

本文采用自传播高温合成方法制备了CuEu0.01Fe1.99O4和CuEu0.01Sc0.01Fe1.98O4纳米粒子，并报道了制备样品的结构、微观结构和磁性能。x射线衍射(XRD)证实尖晶石具有空间群Fd3m的立方结构。平均晶粒尺寸在20 ~ 40 nm之间。扫描电镜(SEM)研究表明了多孔性和颗粒团聚性。利用能量色散x射线能谱仪(EDS)研究了样品的元素组成。磁滞回线显示出软铁磁性。随着Eu3+和Sc3+浓度的增加，饱和磁化强度、矫顽力和剩磁强度等磁性参数降低。

期刊介绍： International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
