This study focuses on the synthesis and comprehensive characterization of ternary NiFe2O4/MnFe2O4/CeO2 nanocomposites. A suite of analytical techniques, including X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), Fourier-transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET) surface area analysis, and magnetic property measurements, was employed to assess structural, morphological, compositional, surface, and magnetic properties. Calcination temperature (600–800 °C) increased particle size and magnetic behavior while reducing BET surface area, suggesting suitability for biomedical and magnetic storage applications.

A suite of analytical techniques, including X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), Fourier-transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET) surface area analysis, and magnetic property measurements, were employed to investigate the structural, morphological, compositional, surface, and magnetic properties of these materials. A systematic approach was implemented for the synthesis of the nanocomposites. FE-SEM analysis revealed the morphology and size distribution of the nanoparticles, while XRD confirmed the formation of the cubic phase within the nanocomposites. An increase in calcination temperature (from 600 to 800 ◦ C) resulted inan increase in average particle size (11, 12 and 22 nm). FTIR and XPS techniques were utilized to study the chemical bonding and surface composition, respectively. BET analysis demonstrated a substantial surface area, however, the surface area decreased with increasing calcination temperature (37.17, 13.7, and 4.16 m2/g). Magnetic property measurements revealed an enhancement in magnetic behavior (2.88, 6.65, and 10. 54 emu/g) with increasing calcination temperature, indicating potential applications in biomedical and magnetic storage fields. All in all, this work highlights the potential of NiFe2O4/MnFe 2O4/CeO 2 ternary nanocomposites for a variety of technological applications by illuminating their complex characterization. | | 1. Introduction Nanocomposites and ferrites have garnered significant attention in advanced materials research due to their unique properties and promising applications [1–10]. Ternary nanocomposites comprising manganese ferrite (MnFe 2O4), nickel ferrite (NiFe 2O4), and cerium oxide (CeO 2) exhibit distinctive magnetic, catalytic, and electrical properties [11,12]. The synthesis of NiFe2O4/MnFe 2O4/CeO 2 ternary nanocomposites leverages the advantageous properties of each individual component. MnFe2O4, for instance, possesses excellent magnetic properties, chemical stability, and low toxicity, making it suitable for applications in biomedical imaging, environmental remediation, and magnetic storage [13–18]. NiFe2O4, with its high magnetic saturation, electrical resistivity, and catalytic activity, enhances the properties of MnFe2O4 [19–21] and expands the potential applications of the composite. CeO2 is well-recognized for its exceptional catalytic activity, high oxygen storage capacity, and reversible redox properties, crucial for environmental and catalytic applications [22–28]. By integrating these three materials into a single nanocomposite, the aim is to maximize their combined benefits and achieve enhanced overall performance. For example, combining catalytic and magnetic properties enables the development of novel materials for environmental remediation, such as magnetically recoverable catalysts for pollutant degradation. Furthermore, the ferrites provide structural stability and enhance the magnetic response, while the redox properties of CeO2 can improve the efficiency of ca
