Abstract:

Lithium ferrite and vanadium-doped lithium ferrite have been extensively studied in recent research because of their potential applications in thermochromic materials, optoelectronic devices, and as a cathode material for rechargeable lithium batteries. In the present investigation, lithium ferrite and lithium vanadium ferrite are synthesized by sol–gel process. According to the Scherrer formula, the average particle size of lithium ferrite is 22 nm and that of vanadium-doped lithium ferrite is 29 nm. The lattice parameters and dislocation density are calculated from the X-ray diffraction resu

Abstract:

Lithium ferrite (Li0.5Fe2.5O4) shows significant promise in electrical and electronic engineering. It possesses a crystal spinel crystal structure denoted as AB2O4, with "A" and "B" representing specific tetrahedral and octahedral lattice sites respectively. Analysis of X-ray diffraction (XRD) patterns aligns well with the JCPDS card (no. 38-0259), confirming the spinel structure with the Fd3m space group. However, an additional peak at 211 in the basic lithium ferrite suggests a subtle Fd3m to the P4132 phase change with a minor secondary hematite phase. Investigating the cation distribution

The structural and magnetic properties of lithium-zinc ferrite ceramics of Li0.4Fe2.4Zn0.2O4 composition, which was obtained under complex high-energy action based on the use of mechanical activation of Fe2O3-Li2CO3-ZnO initial reagents mixture in AGO-2C planetary mill and subsequent its heating to a sintering temperature of 1050 °C for 140 min by ELV-6 continuous electrons beam with an electron energy of 1.4 MeV, were investigated. X-ray phase analysis showed a broadening of diffraction peaks due to the decrease in the crystallite sizes and the increase in the values of microdeformation as a

The samples were sintered at 1150[Formula: see text]C for optimum parameters at chemical reaction between ferrite–ferroelectric interfaces. The presence of ferroelectric nature was detected by X-ray diffraction (XRD) and homogenous coarseness nature was confirmed by scanning electron microscope (SEM). Dielectric measurement for the samples show the superimposition behavior of both magnetic and electric phases in the composite samples. This fact was further supported by magnetic

Abstract:

The influence of the cooling rate during sintering of lithium-titanium-zinc-manganese spinel ferrite on its structural, magnetic and electric characteristics was studied. The ferrite was sintered in air at 1283 K for 120 min. Cooling rates were 0.06 K/s and 7.8 K/s. It was established that the observed changes in the characteristics when using slow and quenching cooling are due to the different levels of the near-surface ferrite layers oxidation. For quench ferrite, the Curie temperature of 530 K, the activation energy of electrical conductivity of 0.35 eV in the bulk of the samples, and the m

Mn substituted copper ferrites (MnxCu1-xFe2O4, x = 0, 0.33, 0.67, 1.00) have been synthesized from metal nitrates and citric acid by sol-gel method (chemical process). This study aims to know the effects of Mn substitution on structural, magnetic, and electrochemical properties of copper ferrites. For characterizing the prepared ferrites, different techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared (FTIR) spectroscopy were used. In addition, vibrating sample magnetometer (VSM) is used to investigate the magnetic properties such as sat
