Abstract

Nanocrystalline Ni_1−xZn_xFe₂O₄ 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 Ni_1−xZn_xFe₂O₄ ferrite calcined at 600 °C for 1.5 h is about 30 nm. Lattice parameter and specific saturation magnetization M _s of nanocrystalline Ni_1−xZn_xFe₂O₄ ferrite increase with the Zn²⁺ ions content at room temperature, and maximum M _s is 66.8 A · m² · kg⁻¹ as the Zn²⁺ ions content is around 0.5, and coercivity H _c of the nanocrystalline Ni_1−xZn_xFe₂O₄ ferrite decreases with Zn²⁺ ions content.
