Effect of Nonmagnetic Doping on Dielectric Properties and Initial Permeability of Ba-Ni Ferrite Nanoparticles by Virtue of Zn2+ Ions

Abstract

The effects of composition, temperature, and frequency-dependent dielectric properties of barium-nickel-based ferrites have been investigated. The conventional ceramic technique prepared the compositions BaNi2-xZnxFe16O27 (at x = 0.0, 0.4, 1.2, and 2). The analysis of X-ray diffraction patterns showed that they were single-phase. The average grain size, lattice constant, and density were found to increase as Zn2+ ion substitution increased. According to the frequency and Zn concentration, the dielectric parameters were properly set. Overall, the dielectric properties of this sample make them a suitable candidate for flexible supercapacitors and are best suited for high-frequency region applications. The initial magnetic permeability of the prepared sample was increasing as the Zn ion contents increases. The produced samples were suitable for application as microwave absorbers, data storage appliances, and magnetic recording mediums.

Optical Properties Behavior of Barium W-type Ferrite doping by Zinc

“…In general, nickel ferrites preferred to occupy octahedral sites, whereas zinc ferrites prefer to occupy tetrahedral sites. [5]. Within the zinc-substituted Ba (Ni2-xZnx)2Fe16O27, khoreems et al observed that the BaNi-W was as having extremely low permeability, with an increase in permeability and a fall in FMR frequency [6,7].…”

Infrared spectra across the 400-4000 cm−1 range of frequencies were used to investigate the optical properties of BaNi2−xZnxFe16O27 ferrite.…”
