Some useful results about absorbing properties of rare earth doped W-type ferrite BaCoZnCe_x Fe_16-x O₂₇

Sections 1 and 2 of the full paper explain the research mentioned in the title, some of whose results we believe are useful and whose core consists of; "The W-type ferrites, BaCoZnCe_xFe_16-xO₂₇(x =0,0. 05,0. 1,0. 15, 0. 2), were prepared by sol-gel method. We Studyed the Influence on the performance of the Ce³⁺ doped W-type ferrites. We characterized the structures, morphologies, magnetic properties and microwave absorption properties of the samples with X-ray diffractometer (XRD), scanning electron microscope (SEM), vibrating sample magnetometer (VSM) and Vector network analyzer. ". We present the experimental results in Figs 1 through 7 and Tables 1 and 2. These results and their analysis lead preliminarily to thefollowing three useful results; (1) all the samples are W-type ferrites and exhibit paramagnetism; (2) when x =0. 15, magnetic and microwave absorbing performance are both the best; (3) the band width (with respect to - 10 dB reflection loss) is 3.5GHz at a matching thickness of 3. 0 mm and the maximal reflection loss is - 11. 34 dB.
