Barium

Barium ferrite (BaO ⋅ 6Fe 2 O 3) belongs to the hexagonal magnetoplumbite-type ferrites with the easy direction for magnetization collinear with the c-axis perpendicular to the flat basal plane. It has widely been used for permanent magnets because of its high coercive force such as 3.2–4.8 × 10 5 A m − 1 (4000–6000 Oe) due to the high magnetocrystalline anisotropy.
