摘要

In this study, an exchange coupled composite (ECC) film with an antiferromagnetic sandwich structure L1_0-FePt/[Co/Ni]_5/Ru/[Co/Ni]_(10) (FePt-CN-Ru) is prepared via dc magnetron sputtering and measured by vibrating sample magnetometer. The results show that FePt-CN-Ru film exhibits ECC characteristics, with excellent angular tolerance, low remanance magnetization, and a narrow switching field. Its thermal stability is higher than that of conventional ECC film. Finally, magnetization reversal is demonstrated through micromagnetic simulation.
