The electrodeposition of Co-Fe and Co-Ni alloys, which can be applied to the magnetic materials for records, has been noticed in recent years, since this method have been the economical and simple process in comparison with other method such as chemical vapor deposition and spattering.In such situation, we have prepared the thin film of Co-Fe and Cc-Ni alloys by the electrodeposition. Moreover, we have specified the optimum experimental condition on the preparation of these alloys and analyzed the lattice structure and surface morphology of them. The composition of these alloys prepared in this work only depends on that of the electrolyte bath. Then, the deposition behavior on this preparation shows anomalous type. Based on this result, we have selected the copper single crystal [Cu (100), Cu (110), Cu (111)] as a substrate, which would enable the epitaxial growth of these alloys, from the viewpoint of misfit to C axis of cobalt. In Co-Fe system, the thin film prepared on Cu (100) and Cu (110) has poly-crystal. On the other hand, that on Cu (111) has the strongly orientation. These knowledge obtained in this work indicate the possibility to the practical application of electrochemical graphoepitaxy of Co-Fe or Co-Ni alloys.

近年来，可以将Co-FE和Co-NI合金的电沉积（可以应用于磁性材料以进行记录），因为与其他方法相比，这种方法是经济且简单的过程。此外，我们已经指定了这些合金制备的最佳实验条件，并分析了它们的晶格结构和表面形态。这些合金在这项工作中制备的合金的组成仅取决于电解质浴的成分。然后，这种制剂上的沉积行为显示出异常的类型。基于此结果，我们选择了铜单晶[Cu（100），Cu（110），Cu（111）]作为底物，从不合适的角度来看，这将使这些合金的外延生长能够在Cobalt的C轴上的观点。在Co-FE系统中，在Cu（100）和Cu（110）上制备的薄膜具有多晶状。另一方面，在Cu（111）上具有强烈的方向。在这项工作中获得的这些知识表明，二氧化合物或二氧化合物的电化学图形上的实际应用可能性。
