This study manifests the outcomes of varying vanadium (V) concentration in Mn–Zn ferrites with the general composition Mn_0.6Zn_0.4V_xFe_2−xO₄ (x = 0.00—0.10, in steps of 0.02) synthesized by the solid-state reaction method. X-ray diffraction (XRD) analysis of all the samples confirmed the formation of the spinel structure. The cell parameter slightly decreases with the increase in V content. The substitution of V noticeably enhanced densification in samples sintered at 1250 °C. The grain size of the starting compositions varied from 13.0 to 27.9 µm. The Fourier Transform Infrared (FTIR) spectra indicate the preference of vanadium ions at octahedral sites. The saturation magnetization (M_s) and the experimental magnetic moments n_B (µ_B) are observed to increase for x = 0.02 with = \({M}_{\mathrm{S}}\)61.73 emu/g. This happens for the reduction of the A–B interaction in the AB₂O₄ spinel type ferrites. After that, M_s and n_B (µ_B) values decreased for higher V contents. The magnetization obtained is explained by redistribution of cations in the tetrahedral and octahedral sites and spin canting due to weakening of exchange interaction. The magnetic permeability and dielectric constant show a decreasing trend with increasing V concentration. The Cole–Cole plots demonstrate the grain and grain boundary effects. The manifestation of single semicircle after x = 0.06 indicates the precedence of grains in the overall resistance. The complex modulus graphs were also studied to understand the mechanism of the electrical processes.

这项研究表明，Mn-Zn铁氧体中钒（V）浓度变化的结果具有一般成分Mn _0.6 Zn _0.4 V _x Fe _{2- x} O ₄（x 固相反应法合成的α＝ 0.00-0.10，以0.02为步长）。所有样品的X射线衍射（XRD）分析证实了尖晶石结构的形成。电池参数随着V含量的增加而略有降低。在1250°C烧结的样品中，V的取代显着增强了致密化。起始组合物的晶粒尺寸为13.0至27.9μm。傅立叶变换红外（FTIR）光谱表明钒离子在八面体位点的偏爱。当x  = 0.02时，随着=  \（{M} _ {\ mathrm {S}} \}，观察到饱和磁化强度（M _s）和实验磁矩n _B（µ _B）增大。61.73 emu / g。发生这种情况是为了减少AB ₂ O ₄尖晶石型铁氧体中的AB相互作用。此后，对于更高的V含量，M _s和n _B（µ _B）值降低。通过阳离子在四面体和八面体位点的重新分布以及由于交换相互作用减弱而引起的自旋倾斜来解释获得的磁化强度。随V浓度的增加，导磁率和介电常数呈下降趋势。科尔-科尔图显示了晶粒和晶界效应。x之后的单个半圆的表现 = 0.06表示晶粒在总电阻中的优先级。还研究了复数模量图以了解电过程的机理。
