摘要： The present invention discloses a single-layered recording film with perpendicular magnetic anisotropy. The single-layered recording film includes a substrate and a ferromagnetic layer. The ferromagnetic layer is formed on the substrate and annealed by a rapid thermal annealing process. After annealing, the average grain size of the single-layered recording film is close to the film thickness of ferromagnetic layer, which is beneficial to achieve a single-layered recording film with perpendicular magnetic anisotropy.

摘要： The present invention discloses a discontinuous islanded ferromagnetic recording film with perpendicular magnetic anisotropy. The discontinuous islanded ferromagnetic recording film includes a substrate and a ferromagnetic layer. The ferromagnetic layer is formed on the substrate and annealed by a high-temperature vacuum annealing process. After annealing, a surface energy difference existed between the ferromagnetic layer and the substrate turns the ferromagnetic layer into well-separated and discontinuous islanded ferromagnetic particles. Each islanded ferromagnetic particle is thought of a single magnetic domain, which is beneficial to achieve a discontinuous islanded ferromagnetic recording film with perpendicular magnetic anisotropy.
