In the sol-gel combustion method, the types of precursor used to manufacture magnetic nano powder, are so important. Among these, the coordinated agent has affected particle size, calcination temperature and the magnetic properties of hexagonal barium ferrite nano powder. By considering the role of coordinating agents on the magnetic properties of particles produced by the sol-gel combustion method, in this paper, the effects of coordinated agents, such as citric acid and glycine during the sol-gel combustion step, on the structural, phase and magnetic properties of produced ferrite powders, were studied. The resultant powders were investigated by XRD, SEM and VSM measurement. The single domain size of BaFe$_{12}$O$_{19}$ powder with crystallite sizes less than 31nm was produced using a glycine precursor and 900$^\circ$C as the sintering temperature.
