Rare Earth Ce3+ Substituted Nickel-Zinc Nano Ferrite were synthesized Calculated Chemical Formulation Ni0.2Zn0.8CexFe2-xO4 (0.000 ≤ x ≤ 0.040) by Citrate-Gel Auto Combustion method at lower temperature. The Single-Phase Cubic Spinel Structure was confirmed by the Characteristic of X-ray diffraction analysis (XRD). The SEM Micrographs confess from typical grain size and surface pattering of the samples is nanometric range confirming the nano crystalline nature. Energy Dispersive Spectrometer (EDS) were used to conduct elemental analysis and elemental parentage. Thermo electric power (TEP) of the prepared samples has been obtained using differential method with high temperature studies carried out in cooling cycle. The electric conductivity at high temperatures using two probe methods. The activation energy in the paramagnetic region (EP) is found greater than the ferrimagnetic region (EF). The carrier concentration(n), charge Carrier Mobility (μ) was carried out by TEP and electric conductivity Studies.
