SrFe12O19 Targets for Pulsed Laser Deposition

Introduction to the properties of SrFe12O19 thin films

SrFe12O19 is a magnetic material with excellent magnetic and electronic properties, making it a promising material for various applications. In thin film form, it is particularly useful for making magnetic films for spintronic devices, magnetic sensors, and high-density magnetic recording media.

Magnetic and Electronic Properties of SrFe12O19

SrFe12O19 has a high magnetic anisotropy and saturation magnetization, making it a strong magnet. It also has a narrow bandgap, which allows for efficient spin-polarized transport of electrons. These properties make it a good candidate for spintronic applications.

Comparison to Similar Materials

SrFe12O19 has better magnetic properties than other similar materials, such as barium hexaferrite and strontium ferrite. It also has a higher Curie temperature than these materials, which makes it more stable at high temperatures.

Crystal Structure of SrFe12O19

SrFe12O19 has a hexagonal crystal structure with alternating layers of Fe3+ and Fe2+ ions. The Fe3+ ions form octahedral sites, while the Fe2+ ions occupy both tetrahedral and octahedral sites. The crystal structure of SrFe12O19 is responsible for its unique magnetic properties.

Typical Substrates for Epitaxial Growth of SrFe12O19

Some substrates that have a good lattice match with SrFe12O19 and are commonly used for epitaxial growth include (but are not limited to) MgO, Al2O3, and SrTiO3. Post deposition annealing causes enhanced crystallization in films and a significant increase in coercivity.
