| 摘 要： | 采用恒电位双电解槽法在硼酸镀液体系中，以单晶Si(111)为基底电沉积制备Co／Cu多层膜，确定了双槽法制备多层膜的工艺条件，为得到优良的多层膜巨磁阻材料，镀液体系中加入了自制的添加剂。并用扫描电镜(SEM)表征了多层膜的断面形貌，小角度X射线衍射(LXRD)谱图中出现了2个衍射峰，大角度X射线衍射(MXRD)谱图中强衍射峰的两侧出现了卫星峰，表明多层膜具有超晶格结构。用物性测量系统(PPMS)测试了Co／Cu多层膜的巨磁阻(GMR)性能，GMR值达到52．52％。

| Abstract: | Co/Cu multilayers were prepared by using double-bath method containing boric acid solution. The technological conditions were determined by cathodal polarization curves of Si(111) electrode in plating solution with different concentration of Cu~(2+) or Co~(2+).Two diffraction peaks in the LXRD indicated that the multiplayer has periodic structure,and satellite peaks in the MXRD patterns indicate that the multilayer has formed a superlattice structure.Which was confirmed by cross-section SEM image of Co/Cu multilayers. in addition,GMR measured by physical property measure system was high up to 52.52%. |
