The analysis of SrO.6Fe2O3 single phase has been performed by using General Structure Analysis System (GSAS) and its magnetic properties has been measured by using Vibrating Sample Magnetometer (VSM). The SrO.6Fe2O3 magnetic material system is synthesized by solid state reaction method through the mechanical alloying process and sintered at 1200 °C for 10 hours. The refinement result of x-ray diffraction showed that the single phases of the SrFe12O19 magnetic material system is formed with the hexagonal crystal structure (space group P 63/mmc), lattice parameters a = b = 5. 9033(5) Å and c = 23.239(2) Å, α = β = 90°, γ = 120o, cell unit volume 701.3(1) Å3, and atomic density of ρ = 5.72 g.cm-3. The hexagonal structure with space group P 63/m m c is constructed from 4 building blocks, namely two S blocks (Fe63+O8 2-)2+ and two R blocks (Sr2+Fe63+O112-)2-. The result from magnetic properties measurement showed that the sample has coercive field, saturated magnetization, and remanence magnetization of 1650 Oe, 63.01 emu/g and 48.21 emu/g respectively.Keywords: SrO.6Fe2O3, Mechanical milling, Crystal structure, Magnetic properties.
