    (Elsevier, 2022) Yener, Tuba; Araz, Isa; Kirsoy, Ahmet; Yalcin, Orhan; Okutan, Mustafa; Bolivar, Peter Haring
    In this study Ce3+ -Cu2+ doped barium hexaferrite Ba-0.5 Ce0.5CuFe11O19 composite sample was synthesized by a conventional method and barium hexaferrites/CeO2 phase composition, X-Ray Diffractometer were examined. Sample morphology was observed by SEM. A VSM was used to analyze the magnetic properties of the ferrites. Complex permittivity, permeability, reflection loss, absorption loss and shielding effectiveness were analyzed by using a VNA measuring the transmission/reflection coaxial airline method. The phase changes of the crystal structure because of the effect of Ce3+ ions into Ba2+ site and Cu2+ ions into Fe3+ areas were investigated. The resulting composition in these two resonance phases has a maximum absorption loss value at similar to 6.48 GHz and similar to 11.25 GHz and a maximum reflection loss value at the same frequencies. In this synthesized composition structure, it has been observed that it has a maximum reflection loss value of approximately -22.2dB and the highest shielding effectiveness value of 33.3 dB at microwave frequency 11.25 GHz.
