In this study, MgFe₂O₄ nanoparticles were successfully prepared through one-pot synthesis using Cajanus cajan (L.) Millsp. Leaf extract (CLE) as a source of weak bases and stabilizing agents. The optical property, structure, morphology, and particle size of the nanoparticles were analyzed. Several characterizations were performed to investigate the formation of nanoparticles. The absorption peaks at 576 cm⁻¹ and 427 cm⁻¹ were attributed to Mg–O vibration stretching at the tetrahedral (8a) site and Fe–O vibration stretching at the octahedral site (16d) of MgFe₂O₄ spinel structure, respectively. The most prominent diffraction pattern of MgFe₂O₄ with a spinel structure was found at 2θ = 35.55 in the crystal plane (311). The optical bandgap of MgFe₂O₄ was obtained to be 2.12 eV. The values of Hc, Mr, and Ms were 110.38 Oe; 1.4 emu/g; and 13.74 emu/g, respectively. All characterizations are in good agreement that MgFe₂O₄ nanoparticles were formed with a spherical shape with a particle size distribution of approximately 12–20 nm. Importantly, we designed a simple, cost-effective, and eco-friendly approach for synthesizing MgFe₂O₄ nanoparticles.

在这项研究中，使用Cajanus cajan（L.）Millsp通过一锅法合成成功地制备了MgFe ₂ O ₄纳米颗粒。叶提取物（CLE）作为弱碱和稳定剂的来源。分析了纳米粒子的光学性质，结构，形态和粒径。进行了一些表征以研究纳米颗粒的形成。分别在576 cm ^-1和427 cm ^-1处的吸收峰分别归因于MgFe ₂ O ₄尖晶石结构的四面体（8a）处的Mg–O振动和八面体（16d）处的Fe–O振动。。MgFe ₂的最显着衍射图在晶面（311）中发现具有尖晶石结构的O ₄在2θ＝ 35.55。MgFe ₂ O ₄的光学带隙为2.12eV 。Hc，Mr和Ms的值为110.38 Oe；1.4 emu / g；和13.74 emu / g。所有的特征都与MgFe ₂ O ₄纳米颗粒形成球形，粒径分布约为12–20 nm完全一致。重要的是，我们设计了一种简单，经济高效且环保的方法来合成MgFe ₂ O ₄纳米颗粒。
