| Abstract | ||
| In the present work, the Ni-La ferrite chain (NiLaxFe2-xO4) with (x=0.0- 0.2),were synthesized using sol-gel auto-combustion as a modern chemical methods. Nitrates, citric acid and ammonia were used in order to get ferrite nano powders at temperature of (200)oC, which characterized a higher dispersion and homogeneity with particle size in the range of (20-39) nm. The dielectric properties are measured using (LCR) meter in the frequency range of (50Hz –5MHz). Dielectric constant (εr'), the loss tangent ( tanδ ) and the loss factor (εr′′) are decreases with increasing frequency, while the Conductivity (σa.c) increases with increasing the rare earth ion (La) concentration in Ni ferrite. | ||
