Synthesis and characterization of (Ba0.2La0.8)Fe 0.2Mn0.4Ti0.4O3 absorbing material by mechanical alloying process has been performed. The absorbing material was prepared by oxide materials, namely BaCO3, La2O 3, TiO2, Fe2O3, and MnCO 3. The mixture was milled for 10 h and then sintered at a temperature of 1000 ° C for 10 h. The refinement results of x-ray diffraction pattern of lanthanum manganite substituted with barium showed that the sample consisted of two phases, namely, La0.9125MnO3 phase which has a structure monoclinic (I12/a1) with lattice parameters a = 5.527(1) Å, b = 5.572(1) Å and c = 7.810(1) Å, α = γ = 90° and β = 89.88(5)°, the unit cell volume of V = 240.57(8) Å3, and the atomic density of ρ = 6.238 gr.cm-3. The microstructure analyses showed that the particle shapes was polygonal with the varied particle sizes of 1 ∼ 3 μm distributed homogeneously on the surface of the samples. The results of the electromagnetic wave absorption curve analysis by using a vector network analyzer (VNA) showed that the sample can absorb microwaves in the frequency range of 8-15 GHz with a very wide absorption bandwidth. It indicates that the as prepared absorber presents potential absorbing property in X and Ku-band. We concluded that the (Ba 0.2La0.8)Fe0.2Mn0.4Ti 0.4O3 material can be applied as a candidate absorber material of microwaves or electromagnetic wave.
