Introduction 

Barium Ferrite Thin Film Target

Barium ferrite (BaFeO3) is a well-known magnetic material with a unique combination of high magnetocrystalline anisotropy and low coercive field, which makes it an attractive material for a variety of magnetic applications, including magnetic data storage, microwave devices, and spintronics.

Optical and Chemical Properties of Barium Ferrite

Barium ferrite is an insulating material with a high dielectric constant and a relatively low refractive index. It has a complex crystal structure with a hexagonal unit cell and a space group of P63/mmc. The material exhibits magnetic ordering at room temperature and has a magnetic moment of 2.9 Bohr magnetons per formula unit.

Comparison to Similar Materials

Barium ferrite has a unique combination of magnetic and optical properties that distinguish it from other similar materials, such as iron oxide, cobalt ferrite, and nickel ferrite. In particular, barium ferrite has a higher magnetocrystalline anisotropy and a lower coercive field than these other materials.

Crystal Structure of Barium Ferrite

The crystal structure of barium ferrite is hexagonal with a space group of P63/mmc. The unit cell contains one formula unit, which consists of one barium atom, one iron atom, and three oxygen atoms.

Typical Substrates for Epitaxial Growth of Barium Ferrite

Barium ferrite can be epitaxially grown on a variety of substrates, including sapphire, silicon, and strontium titanate. Substrates with a good lattice match, such as strontium titanate, can improve the quality of the resulting thin film.
