ABSTRACT
Soft/hard bilayers consisting of a FeAu layer with different thicknesses and a 20 nm L10-FePt layer have been fabricated by magnetron sputtering and postannealing. FeAu soft layer not only can promote the ordering degree of FePt layer because of the small lattice mismatch between them and the diffusion of Au atoms into FePt boundaries, but also can reduce the coercivity due to the soft/hard exchange coupling. The results of x-ray photoelectron spectroscopy indicate that a graded interface is formed in the FeAu/FePt bilayer after annealing, which is beneficial to reduce the pinning field. The magnetization reversal in the FeAu/FePt exchange-spring media occurs by the nucleation and propagation of a domain wall from soft layer into hard layer.
