Abstract

• Rare earth, ytterbium doped inc ferrites (n(YbxFe1-x)2O4 ) with x=0.0000, 0.0125, 0.0250, 0.0375 and 0.0500 have been prepared by the solid state method. The raw materials such as ytterbium oxide, zinc oxide and ferrite oxide have been used as the source materials. The spinel ferrite structure, cubic morphology, and the identification of functional groups of the ytterbium doped zinc ferrite have been analyzed systematically using several analytical tools. The resistivity decreases in the sample without RE dopants for both frequency regions of(10 kHz-100 kHz)and(1MHz10MHz). Moreover, rare-earth doped samples exhibit high conductivity than undoped zinc ferrite. The electrical conductivity at room temperature is directly proportional to the reaction rate of samples.
