摘　　要：由Miedema半经验公式计算的Fe/Y二元系自由能图 ,及退火时Fe/Y非晶多层膜晶化过程的XRD分析结果得出 :Fe、Y晶态自由能低于初始非晶态为晶化提供驱动力 。The free energy diagram of Fe/Y system was calculated by means of Miedema's semi\|empirical theory.Crystallization of the multilayer with an amorphous microstructure was investigated by XRD after annealing.The free energies of crystalline Fe and Y phase are smaller than those of amorphous ones,which supply the thermodynamic driving force for the crystalization.Phase evolution of the multilayer is controlled by free energy barrier and radius of critical nucleus in Fe/Y system.
