摘　　要：采用磁控溅射法制备了[FePt/Ta]5Ta多层膜,通过XRD检测样品为单相L10结构,没有发现杂相.利用Preisach模型得到的结果和实验一致,并在此基础上研究了单场磁后效行为.[FePt/Ta]5Ta multilayers were grown on Si substrate by reactive magnetron co-sputtering. X-ray difffraction measurement revealed that the multilayer films were single phase. The ferromagnetic hysteresis curves were simulated by using Preisach model. Magnetism aftereffect was studied on the basis of ferromagnetic hysteresis curves.
