Terbium Iron Garnet (Tb3Fe5O12) PLD Target

Introduction to Terbium Iron Garnet

Terbium Iron Garnet (TIG) is a ferrimagnetic material with the chemical formula Tb₃Fe₅O₁₂. It is a type of garnet structure and has excellent magnetic and optical properties, making it a popular material for use in various thin film applications. TIG is typically used in the form of thin films, which can be grown on different substrates using pulsed laser deposition.

Structural and Magnetic Properties of Terbium Iron Garnet

TIG has a cubic crystal structure with a lattice parameter of approximately 12.4 Å. It has a high magnetization and a Curie temperature of around 570 K. TIG also exhibits magneto-optical effects, making it useful in applications such as magnetic sensors and optical isolators.

Comparison with Similar Materials

Compared to other ferrimagnetic materials such as yttrium iron garnet (YIG) and gadolinium gallium garnet (GGG), TIG has a higher Curie temperature and a larger magneto-optical figure of merit. TIG also has a higher magnetization than YIG, making it more suitable for high field applications.

Crystal Structure of Terbium Iron Garnet

TIG has a cubic crystal structure with the space group Ia3d. The structure consists of two interpenetrating lattices of iron and terbium ions, with oxygen ions occupying the tetrahedral and octahedral sites between them.

Typical Substrates for Epitaxial Growth of Terbium Iron Garnet

TIG can be epitaxially grown on various substrates such as gadolinium gallium garnet (GGG), yttrium iron garnet (YIG), and magnesium oxide (MgO), which have a good lattice match with TIG.
