Synthesization and magnetic properties of Ba1−xYxFe12O19 hexaferrites prepared by solid-state reaction method. The saturation magnetization (σs) and coercivity (Hcj) of the Ba(1−x)YxFe12O19 ( x=0.00, 0.02, 0.05, 0.08, 0.10, 0.13) magnetic powders with different Yttrium aggregation (x) were determined. The saturation magnetization (σs) was decreased whereas coercivity (Hcj) was increased. The magnetic properties of the magnet at x=0.13 reached the maximum values. Lattice constants (c) for all the samples are different but lattice constant (a) remains almost same. The saturation magnetization (Ms) was very low, while coercivity (Hc) was high.
