摘要

A micromagnetic simulation analysis is systematically carried out to explore the magnetization reversal mechanism, residual stress and exchange interaction in L1_0-FePt/Au nanocomposite films with perpendicular magnetic anisotropy. Results show that: (1) the domain-wall pinning mode is the main mechanism responsible for magnetization reversal in L1_0-FePt/Au films; (2) considering the magnetoelastic energy produced by lattice mismatches between Au and FePt, the simulated out-of-plane loop matches the experimental loop very well. The residual tensile stress in the films is quantitatively described by both experimental calculations and micromagnetic simulations; (3) the exchange interaction within FePt grains of the films is strong, which allows for the coherent switching of the magnetization moments of an FePt grain.
