NiFe films with a composition gradient are of particular interest from the point of view of fundamental science and practical applications. Such gradient magnetic structures may exhibit unique functional properties useful for sensory applications and beyond. The issue surrounds the anomaly concerning the compositional gradient formed near the substrate in electrolytically deposited binary and ternary iron-containing alloys, which has not previously been clearly explained. In this work, light is shed on this issue, and a clear relationship is found between the structure and surface properties of the substrate, the initially formed NiFe layers and the film composition gradient.
从基础科学和实际应用的角度来看，具有成分梯度的镍铁薄膜特别受关注。这种梯度磁性结构可能表现出对传感应用及其他领域有用的独特功能特性。问题围绕着在电解沉积的二元和三元含铁合金中靠近基底形成的成分梯度异常，此前尚未得到明确解释。在这项工作中，这个问题得以阐明，并且发现基底、最初形成的镍铁层的结构和表面性质与薄膜成分梯度之间存在明确的关系。
