X-ray diffraction (XRD) analysis confirmed the successful synthesis of cubic spinel ferrite across all the studied compositions, whereas structural changes, such as lattice size, porosity and crystallite size, exhibited compositional dependence. Scanning electron microscopy (SEM) of the pellet surfaces revealed the dependence of the grain size distribution and porosity on the zinc content. Raman spectroscopy analysis allows the determination of the distribution of cations as a function of the Zn content, revealing the change from an inverse to a mixed spinel structure. X-ray photoelectron spectroscopy (XPS) allows the determination of the cations of Ni²⁺, Ni³⁺, Fe²⁺ and Fe³⁺ distributed in tetrahedral and octahedral sites, resulting in new magnetic and dielectric interactions in the samples. Magnetic hysteresis loops confirmed the ferromagnetic ordering of the synthesized ferrites, with saturation magnetization values ranging from 40 to 76 emu/g for 0 to 0.5 mol of Zn, respectively. The observed increases in relative permittivity and conductivity with increasing zinc content are attributed to the redistribution of Fe³⁺ ions within the crystal lattice, which is modulated by the Zn doping level. These findings confirm that bulk zinc-doped nickel ferrites synthesized by high–energy ball milling exhibit improved ferromagnetic and dielectric properties, suggesting potential for expanded technological applications.</p></div>","PeriodicalId":646,"journal":{"name":"Journal of Materials Science: Materials in Electronics","volume":"36 14","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structural, morphological, vibrational, mechanical, optical, surface area and magnetic characterizations were performed using XRD, SEM-EDAX, FTIR-Raman, UV-DRS, BET and VSM techniques. XRD pattern reveals the CuFe₂O₄ spinel cubic phase (<i>Fd3m-227</i>) with trace amounts of CuO and α-Fe₂O₃ phases. The estimated crystallite sizes for as-prepared and annealed samples were found to increase. An agglomerated morphology with irregular shape of particles was observed. Raman spectroscopy identified five vibrational modes of the CuFe₂O₄ phase. FTIR analysis detected tetrahedral and octahedral metal–oxygen modes, providing a deeper understanding of the sample’s mechanical behaviour.

The optical bandgap (~ 1.60 eV) and Urbach energy (~ 0.369 eV) values were very similar for both as-prepared and annealed samples. The samples exhibit semiconducting behavior with significant defect levels, as confirmed by analysis of Urbach energy. The specific surface area of 107.37 m²/g and 74.63 m²/g, and pore size between 6.49 nm and 6.98 nm confirmed the mesoporosity of the prepared samples.

The magnetic saturation decreases while increasing coercive field and magnetic anisotropy as crystallite size increases with an increase in annealing temperature to 400 ºC.

Comprehensive surface characterization techniques, including scanning electron microscopy (SEM), electron dispersive X-ray spectroscopy (EDX), atomic force microscopy (AFM), Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS), were employed to examine the morphological, structural, and chemical properties of the films. SEM–EDX mapping revealed thickness dependent elemental distributions. AFM analysis showed increased surface roughness (1.69 to 2.15 nm) and grain size (60 to 90 nm) with increasing film thickness. XPS measurements conducted at 8-week intervals provided insights into the oxidation behavior of Ag electrodes and their surface chemistry evolution over time. Raman analysis confirmed the presence of anatase and rutile phases in the titanium oxide thin films, as evidenced by the characteristic peaks observed at 196.83 cm⁻¹ and 607.43 cm⁻¹, respectively.
