New chemical synthesis procedure for preparation of nickel-zinc doped W-type hexagonal, nickel-zinc doped barium ferrite nanoparticles has been developed, using the nitrate-citrate sol–gel auto-combustion method (NCSAM). The crystalline phase attributes, microstructure, morphology, thermal behavior of the as-burnt phase and the sintered powders were characterized using XRD, SEM, TG-DTA, FT-IR measurements. The pure W-type ferrite phase is formed during 4 h annealing at a temperature of 1 200 °C.
