Analysis of Crystallography Structure and Magnetic Properties of Microwave Absorbing Material Ba_0.6Sr_0.4Fe_12-3xZn_2xTi_xO₁₉ (X = 0, 0.2, 0.4, and 0.6)

Abstract:

The synthesis and characterization of the Ba_0.6Sr_0.4Fe_12-3xZn_2xTi_xO₁₉ microwave material with x = 0, 0.2, 0.4, and 0.6 has been successfully carried out. Samples were processed with the solid reaction method through milling at seven hundred revolutions per minute for five hours. X-ray diffraction was used to characterize the phase formation and crystal structure. Scanning electron microscopy was used to see the shape and size of particles, while the vibrating sample magnetometer was used to measure magnetic quantities, which are: the coercivity field and magnetic saturation. All samples have a hexagonal structure, for samples x = 0 and 0.2 have a single phase, while for samples x = 0.4 and 0.6 other phases are detected. The shape of the particles are heterogeneous, with size ranging from 10-25 μm. All samples were not saturated even until the external magnetic field reaches 1 T. As the value of x increases, the magnetization will decrease. Samples substituted by Zn and Ti (x ≠ 0) have higher coercivity field values when compared to sample without substitution (x = 0).
