摘要：

Perovskite type ferrite doped with Sr2+, Dy1-xMxFeO3(x = 0.0, 0.05, 0.15, 0.25) were prepared by the conventional solid-state reaction. The structure and electromagnetic properties of the calcined samples were studied using powder X-ray diffraction (XRD, Rigaku D/Max-2500) and network analyzer (Agilent 8722ET). All the XRD patterns showed the single phase of the perovskite type ferrite without other intermediate phase when x <= 0.25. The electromagnetic properties of the samples have been studied at the frequency range from 2 GHz to 18 GHz. The epsilon' and epsilon '' values were improved significantly. Both the values of epsilon' and epsilon '' increase with the increasing content of the doped cations Sr2+, and the peak value of epsilon '' was about 2.2 at 12.1 GHz position when x = 0.25.
