The Microwave Electromagnetic Properties of Sr²⁺ Doped DyFeO₃

Abstract:

Perovskite type ferrite doped with Sr²⁺, Dy_1-xM_xFeO₃(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 ε′ and ε′′ values were improved signiﬁcantly. Both the values of ε′ and ε′′ increase with the increasing content of the doped cations Sr²⁺, and the peak value of ε′′ was about 2.2 at 12.1 GHz position when x = 0.25.
