摘要：

Nanostructured powder of Ni-Zn ferrite was directly produced by high-energy ball milling of stoichiometric mixture of ZnO, NiO, and Fe(2)O(3) powders. X-ray powder diffractometry, scanning electron microscopy, annealing, treatment, and vibrating sample magnetometer were used to investigate the structural, chemical, and magnetic aspects of Ni(0.5)Zn(0.5)Fe(2)O(4) compound. The crystallite size of final product after 60 h of ball milling time was estimated to be 17 nm. Heat treatment of ball-milled Ni-Zn ferrite was performed to study the thermal behavior of ferrite. The effect of copper doping on structure and magnetic properties of Ni-Zn ferrite was also studied. The results showed that the Zn replacement with Cu led to a decrease of magnetization.
