Abstract

The Pr2Fe17−xTix (x = 0.0, 0.1, 0.2, 0.3, 0.4) powder were prepared by arc smelting and high energy ball milling method. The phase structure, morphology, magnetic properties and electromagnetic parameters of the powders were characterized by X-ray diffraction, scanning electron microscopy, vibrating sample magnetometer and vector network analyzer, respectively. The results indicate that the lattice parameter a and c and unit-cell volume V increase linearly with the increasing amount of Ti doping. The saturation magnetization of the Pr2Fe17−xTix alloys decreases with the increase of Ti content. The minimum absorption peak frequency shifts towards higher frequency region upon the Ti substitution. And the minimum reflection loss of the Pr2Fe17−xTix alloys increases with the increase of Ti content. The minimum reflection loss of Pr2Fe16.6Ti0.4 powder reaches about −32.50 dB at 5.36 GHz, and the frequency bandwidth of R < −10 dB reaches about 1.52 GHz with the best matching condition d = 2.5 mm.
