A study of structural and chemical properties of Ni1-xZnxFe2O4 ferrite powder prepared by co-precipitation method

Abstract

Nickel zinc nanoferrites (Ni1-xZnxFe2O4 with x ranging from 0.3 to 0.7 and 0.9) were employed in this study. Chemical co-precipitation was used to synthesize nanoparticles, X-ray diffraction, fourier transform infrared spectroscopy, field emission scanning electron microscopy analysis (FESEM), and the vibration sample magnetometer were used to determine the structure, size, morphology, and magnetic properties of nanostructures (VSM). X-ray diffraction was used to identify the crystalline phases, and all samples have cubic spinel ferrites. To evaluate particle sizes using Scherrer's formula. average crystallite sizes were in the range of (13-19)nm and FTIR spectroscopy data for respective sites were examined in the range of 200–4000 cm-1 . Between 320 and 1000 cm-1 , the formation of ferrite phase was confirmed, indicating the sample's ferrite nature. Tetrahedral complexes were assigned to the higher frequency band ν1, while octahedral complexes were assigned to the lower frequency band ν2. The M-H curve shows that Ms rises from 1.96-23.7 (emu/g).
