Keywords： nanocrystalline material

Nanocrystalline Ni1-xZnxFe2O4 ferrites with 0≤x≤1 were successfully prepared by a spraying-coprecipitation method .The microstructure was investigated by using XRD and TEM .Magnetic properties were measured with vibrating sample magnetometer (VSM) at room temperature .The results show that the grain size of nanocrystalline Ni1-xZnxFe2O4 ferrite calcined at 600 ℃ for 1 .5 h is about 30 nm .Lattice parameter and specific saturation magnetization Ms of nanocrystalline Ni1-xZnxFeO4 the Zn2+ ions content is around 0 .5,and coercivity Hc of the nanocrystaUine Ni1-xZnxFe2O4 ferrite decreases with Zn2+ ions content .
