Abstract: 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.
