In the present work, ferrites with compositions of Ni0.60Zn0.40-xRexFe2O4where x=0.05, 0.10, 0.15 were prepared by conventional Solid State Reaction Method. The samples were pre sintered at 10000 C for 4 hours in air and sintered at 12500 C for 3 hours. The influence of Lanthanum (la) substitution on various properties of Ni-Zn ferrites have been studied in this work. Investigations were carried out by the measurements of AC resistivity, Permeability and Curie temperature of the sample. AC resistivity has been found to be decreased of the samples. The initial magnetic permeability remains constant up to 10 MHz thenceforth sharply fall to very low values at higher frequencies and again remain constant from 9 MHz to 120 MHz and onward due to Zn deficient of Ni -Zn ferrites with substituting of La. The sharp directress of permeability at T = Tc indicates the samples good homogeneity. The TC is found to increase with increasing Zn-deficient by substituting rare earth metal lanthanum (La).
