Abstract:
In this paper, we have reported the comparison of structural, optical and electrical properties for NixZn1-xFe2O4 and MgxZn1xFe2O4 nano-particles. These nano-particles (x= 0.2, 0.4, 0.6, 0.8 and 1.0) were prepared by co-precipitating aqueous solutions method using identical preparation conditions. The XRD patterns shows that both samples consisted of six peaks and related to (220), (311), (400), (422), (333), (440) planes of a cubic unit cell respectively and are in close agreement with characteristic peaks of soft ferrites. The particle size of MgxZn1-xFe2O4 was found to be decreasing from 31.32 to 19.55 nm by increasing magnesium content. While the particle size of NixZn1-xFe2O4 samples varied from 30.86 to 34.59 nm. The values of Lattice constant, volume, x-ray density, bulk density, particle size, porosity and dielectric constant, loss tangent and ac conductivity were also calculated for both series and results were compared. In conclusion our results suggested that MgxZn1-xFe2O4 can be a suitable replacement for NixZn1-xFe2O4 upto 3 MHz.
