Abstract
The effect of Mechanical Alloying (MA) process on properties of Ni-Zn soft ferrite was investigated. Raw material powder treated by MA was found to be amorphous structure by using x-ray diffraction and synchrotron radiation analysis. In the case of Ni-Zn soft ferrite treated by MA process, the spinel formation by heating tends to start at 300°C as low as that treated by normal process. The spinel formation in MA treated powder is carried out with a heat generation, which shows a remarkable contrast with that of normal process. MA treated Ni-Zn soft ferrite was found to have higher initial permeability at higher frequency as compared with normal ferrite. It may be attributed to the smaller density after sintering arises from the presence of many micro pores. If a MA treated ferrite with less micro pores and the very fine structure can be obtained, it would be expected to improve the magnetic properties in higher frequency.
