ABSTRACT:
Zirconium (Zr4+) doped nickel- zinc ferrite nanoparticles with chemical composition of ZrxZn0.5-xNi0.5-xFe2O4 (0.1=x=0.30) have been synthesized successfully by sol–gel auto combustion method using urea as a fueling agent. XRD study confirms the single phase formation of composite ferrite which belongs to cubic spinel structure and the lattice parameter found to be a= 8.417, 8.44 and 8.452Å for the respective values of x = 0.10, x = 0.20, x = 0.30. TEM study reveals the morphology of Ni-Zn ferrite nanoparticles are well spread over wide area. The saturation magnetization gradually decreases with the increase in Zr substitution and reaches minimum when x=0.30 whereas the coercivity value reaches minimum when x=0.10. DC electrical resistivity has been found to vary with increasing Zr content. The good electrical resistivity of ceramic material more than 125 MOcm was used for high frequency transformer applications.
