Abstract:	It was found that the coercivity of the FePt/Fe exchange-coupled granular bilayer reduced after in situ annealing at elevated temperature. With the assistance of Landau-Liftshitz-Gilbert (LLG) micromagnetic simulation, the possible reasons that may lead to the coercivity change, such as the formation of magnetically graded interface and the Fe soft layer capping configuration, were investigated separately. It was found that magnetically graded interface resulted from interface diffusion did not have significant influence on the coercivity. However, the coercivity was reduced dramatically when the Fe magnetically soft layer extended more in the lateral direction. © 2013 AIP Publishing LLC.
