Abstrakt: Nano-ferrite materials with chemical compositions Co0.3Cu0.7Fe2−xCrxO4 (x = 0.0, 0.05, 0.1, 0.15, 0.2, and 0.25) were synthesized through the wet chemical method, and analytical characterizations of their structural, magnetic, and dielectric properties were conducted. The structural formation was confirmed through powder X-ray (XRD) measurements, further affirmed by Fourier transform infrared spectroscopy (FTIR). Microstructural and morphological properties were investigated using FESEM and HRTEM scanning, revealing grains in the nano-scale range. Room temperature vibrating sample magnetometer (VSM) analysis provided magnetic information on the materials, presenting various values of magnetic parameters. Importantly, dielectric properties were examined using an LCR meter, revealing the dielectric nature of the synthesized materials and showing variations in dielectric parameters corresponding to changes in the dopant concentration. These prepared ferrite qualities suggest they could be used in high-density data storage systems, memory, and magnetic recording devices. [ABSTRACT FROM AUTHOR]
