| 摘 要： | 针对Ni80Fe20/Mo纳米多层膜在实际应用中经常面临的热稳定性问题，研究了多层膜在343－683K温度范围内的互扩散行为，测定了其有效互扩散系数Dλ。小的激活焓来源于多层膜中存在的共格应变。当温度低于483K时，NiFe/Mo多层膜具有较强的抵制NiFe和Mo亚层间互扩散能力，这对NiFe/Mo多层膜今后的实际应用有重要意义。

| Abstract: | For improving the thermal stability of magnetic multilayers, the interdiffusion of Ni80Fe20/Mo multilayers between 343～ 683K has been studied by determining the effective interdiffusion coefficient Dλ . The much lower activation enthalpy of diffusion is attributed to the coherence strains existing in the multilayers. As the annealing temperature is below 483K, this result suggests that the Ni80Fe20/Mo multilayers have a strong resistance to the atomic interdiffusion between sublayers. It is signifi－cant to application of NiFe/Mo multilayers. |
