SrFe12O19 thin films were grown on SrTiO3 substrates by pulsed laser deposition.
The as-deposited SrFe12O19 films exhibited low magnetization with poor crystallinity.
Annealed SrFe12O19 films showed crystallites with faceted surfaces.
Annealed SrFe12O19 films on SrTiO3 (111) substrate had a strong magnetic anisotropy.
