NixZn1-xFe2O4 ferrites with initial unit molar ratio of NiO/ZnO were prepared by self-propagating high temperature synthesis (SHS) at the oxygen partial pressures of 0.25 MPa. Neutron diffraction analysis shows that final product is Ni0.38Zn0.62Fe2O4 (χ2=1.68). The combustion temperature and propagating rate were about 1180 K and 4.2 mm/sec, respectively. The ferrite particle size was less than about 350 nm. The coercive force, maximum magnetization, residual magnetization, susceptibility and curie temperature of Ni0.38Zn0.62Fe2O4 powders prepared by SHS are 2878 A/m, 6.805 Wb/m2Kg, 1.27 Wb/m2Kg , 0.042 m3/kg and 42.20 °C, respectively.
