This study investigates the synthesis and structural characterization of the polycrystalline nanocomposite material ytterbium manganate-cobalt chromite (YbMnO3-CoCr2O4). The synthesis was performed using the sol-gel and Pechini methods. X-ray diffraction (XRD) analysis was used to determine the phase composition, revealing the presence of perovskite-type ytterbium manganate and spinel-type cobalt chromite. Data analysis was conducted using the powder diffraction x-ray line (PDXL) program, confirming that the nanocomposite is a two-phase system consisting of orthorhombic perovskite and cubic spinel phases. Morphological analysis was carried out using scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (TEM) to confirm the elemental composition and provide average particle size measurements and their distribution. The particle sizes were determined to be 215-525 nm for YbMnO3 and 2.11-3.19 μm for CoCr2O4. Additionally, 3D surface profiles and nanomaterial growth measurements were obtained using the MP-45030TDI 3D modeling software. This synthesized nanocomposite is significant for spintronic devices and multifunctional sensors.
