dc.description.abstract(Ni0.25Cu0.20Zn0.55)LaxFe2-xO4 ferrite with x =0.00, 0.025, 0.050 and 0.075 compositions were synthesized through nitrate-citrate auto-combustion method. Crystalline spinel ferrite phase with about 16-19 nm crystallite size was present in the as-burnt ferrite powder. These powders were calcined, compacted and sintered at 950oC for 4hours. Initial permeability, magnetic loss and AC resistivity of different compositions were measured in the frequency range from 10Hz to 10MHz. Saturation magnetization and hysteresis parameters were measured at room temperature with a maximum magnetic field of 10 kOe. Permeability and AC resistivity were found to increase and magnetic loss decreased with La substitution for Fe, up to x=0.025. Saturation magnetization and coercive field also increases up to that limit. The electromagnetic properties were found best in the ferrite composition of x=0.025 which would be better for more miniaturized multi layer chip inductor.en
