Al³⁺ and Cr³⁺ co-substituted NiZnCo nano ferrites: synthesis and structural properties

Abstract

The Al3+ and Cr3+ substituted in Ni0.4Zn0.35Co0.25Fe2-x-yAlxCryO4 (x = y = 0.0, 0.05, 0.1, 0.15 and 0.2) ferrite nanoparticles were prepared with sol-gel method. X-ray diffraction (XRD), Field Effect Scanning Microscopy (FESEM), and Fourier Transform Inferred Spectroscopy (FT-IR) were used for their characterization. They have a single-phase spinel structure. The lattice constant decreases with increasing concentrations. Agglomerated small particles with stoichiometric proportions were obtained from FESEM. The region around 600 cm-1 and 400 cm-1 has two absorption bands related to two interstitial sites by FTIR agree with the spinel lattice.

Complex impedance analysis of soft chemical synthesized NZCF systems

“…We have prepared cobalt substituted Ni0.95−xZn0.05CoxFe2O4, (where x = 0.01, 0.02, and 0.03) by easy and cheap soft chemical method and carried their impedance analysis along with dielectric dispersion [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. The structural, morphological, and magnetic properties along with their initial permeability and dielectric constant Ni-Co-Zn were studied recently and published [18,32,33].…”

Co3+ Doped CdFe2O4 Nanoparticles: Structural, Optical, Magnetic, and Electrical Properties

“…Various methodologies, encompassing sol-gel, microemulsion, ball milling, solid-state, hydrothermal processes, co-precipitation, solution-based synthesis, and citrate gel auto-combustion, have been employed for the fabrication of nanomaterials. [9][10][11][12][13] Over the past two decades, magnetic nano materials have garnered significant interest for their unique attributes and applications in low-dimensional scales. Their remarkable magnetization, resistivity, and permeability render them valuable across various technical domains, including sensors, biomedicine, automotive sectors, cooling systems, data storage, and converters.…”
