Abstract

The activation energy of ordering (Q_S) and of atomic interdiffusion at Fe/Pt interfaces (Q_D) was discussed to clarify the formation process of L1₀ Fe-Pt ordered phase in Fe (t _Fe)/Pt (t_Pt) multilayers. It is found that the Q _S takes a minimum of ∼ 0.7. eV when the Fe and Pt layer thicknesses were equal. This value was found to be lower than that of the Fe-Pt single layer and the self-diffusion energy. It shows that the enhanced ordering process of the multilayers was directly correlated with the rapid interdiffusion at the Fe/Pt interface.
