摘要：

The nanocrystalline Ni(0.4)Cu(0.3)Zn(0.3)Fe(2)O(4)ferrite is prepared by sol-gel method by doping Ta2O5(0 to 10 wt%). This paper presents effect of Ta(2)O(5)doping on electrical and dielectric properties of nanocrystalline NiCuZn ferrite. The XRD patterns of the synthesized samples reveal single phase cubic structure and show the secondary phase of FeTaO(4)with increasing Ta(2)O(5)composition. From FESEM, agglomeration of spherical particles is observed. Direct current electrical resistivity is measured by two probe method. The investigated ferrite samples exhibits semiconducting nature property as resistivity decreased with the increase in temperature. The variation of dielectric constant and dielectric loss tangent for all samples are presented as a function of the frequency. The result also shows that as frequency is increased there is an increase in alternating current conductivity at room temperature.
