Tailored electromagnetic properties of NiZn nanocomposite materials

Nickel-zinc ferrite nanoparticles with compositions of Ni_xZn_1-xFe₂O₄, where x = 0.1 - 0.9, were synthesized using a water-based precipitation technique. These nanoparticles were then calcined at high temperature to improve crystallinity and were characterized to determine their magnetic and dielectric properties. After selecting the synthesized composition with the most favorable magnetodielectric properties and dispersing it into a polymer matrix, we can tailor the permeability and permittivity based on the fraction of filler loading. The nanoparticles and nanocomposites were characterized using standard technologies for structural, physical, and electromagnetic properties.
