| 技術摘要 / Our Technology： |
本發明係提供一種具垂直磁異向性之不連續島狀鐵磁性合金薄膜，其包含一基板以及一鐵磁性層。該鐵磁性層係形成於該基板上，其中該鐵磁性層經由一高溫真空熱退火處理後與該基板間存在一表面能差異，該表面能差異使該鐵磁性層形成分布均勻之不連續島狀鐵磁性顆粒，每一該島狀鐵磁性顆粒為一單磁區，藉以獲得一具有垂直磁異向性之不連續島狀鐵磁性合金薄膜。
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.
