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 in these ferrites is crucial for further exploration of their magnetic and dielectric properties. These ferrites find widespread applications in microwave technology and magnetic and electric energy storage devices.

“…Spinel ferrites consists of cubic fcc unit cells having two sites i.e., octahedral (B-site) and tetrahedral (A-site). [7][8][9] Several metal ions may be substituted at these interstitial locations to improve the traits of spinel ferrites and therefore, these materials are particularly sensitive to these substitutions. 10 The different compositions of spinel ferrite might exist based on the different types of elements used as dopants in these interstitial site occupancies.…”

Magnetic nanoparticles of neodymium and samarium substituted Mg-Zn-Cu, with a chemical composition of Mg0.5Zn0.5Cu0.05RxFe1.95-xO4 (x = 0.05; R = Nd, Sm) were produced via the sol-gel auto-combustion route. X-ray diffraction indicates the evolution of a cubic symmetry having Fd3m space group and no impurities at room temperature. Field-emission scanning electron microscopy images show irregularly-shaped and agglomerated grains in all samples. Fourier transform infrared examination reveals stretching vibrations among the metal cations and anions at interstitial vacancies. M-H graphs demonstrate that the prepared nanoferrites have low rentivity (0.18-0.84 emu/g) and coercivity (11.25-34.03 Oe) indicating the formation of superparamagnetic nature. From the electromagnetic traits, the observed sample's real magnetic permeability (μ'') and permittivity (ε’) along with dielectric loss and magnetic loss reduced with increasing applied field frequency, indicating the typical behaviour of spinel nanoferrites. This may be explained by Maxwell-Wagner interfacial polarisation and the electron hopping among the ferrous and ferric ions. The variations in coercivity, anisotropy constant, and electromagnetic traits provide strong evidences that all of the samples are thermally stable and have the potential to be used in solenoids and transformers and also in more resistive devices that operate at high frequency.
