Abstrak

Electromagnetic wave absorber materials with(La0.8Ba0.2)(Mn(1-x)/2ZnxFe(1-x)/2)O3(x = 0-0,6) had been researched. This magnetic material was synthesized by using solid state reaction method and a suitable composition for the application of a microwave absorber material had been obtained, namely (La0.8Ba0.2)(Mn0.4Zn0.2Fe0.4)O3 (x = 0,2).Precursors use wereLa2O3, BaCO3, ZnO, Fe2O3, dan MnCO3. The mixture was mixed with High Energy Milling for 5 hours then sintered at 1000 C for 5 hours.The result of refinement of X-ray diffraction pattern shows that (La0.8Ba0.2)(Mn0.4Zn0.2Fe0.4)O3material had a single phase and a trigonal structure. The surface morphology of the sample had a uniform spherical shape. The results of absorbance analysis of samples to electromagnetic waves in the range of 8-12 GHz was 96%. Thus, the (La0.8Ba0.2)(Mn0.4Zn0.2Fe0.4)O3 (x = 0,2) material was a potential candidate for applications of electromagnetic wave absorber material.
