摘要：

The effect of Co, Cu substitution on the magnetization mechanism of Zn-2-Y hexagonal ferrite was investigated. The samples were prepared by the conventional ceramics method. X-ray diffraction results confirm the well-defined Y-type phase for each sample. The microstructure was observed via scanning electron microscopy, and the magnetic properties were investigated using impedance analyzer. Experimental results show that Co substitution will increase the magnetic anisotropy distinctly. Co substitution will reduce the magnetic domain wall motion and move the resonance peak towards high frequency. Cu substitution will decrease the initial permeability and tune dispersion character in very high frequency efficiently. Proper control of treatment conditions is necessary to improve the magnetic properties. (C) 2003 Elsevier B.V. All rights reserved.
