Ferromagnetic/antiferromagnetic bilayers are used in a number of spintronics devices. With the growth of this area of research and development, as well as its commercial use, the availability of more methods of production is desired. Electroplating may take an important role in this context similar to the one it plays in conventional microelectronics. In the present work, FeMn/Ni bilayer films were electrodeposited from sulfate electrolytes. Copper electrodes were used as substrates in order to induce the growth of the γ-FeMn phase. The samples were potentiostatically deposited and the composition of the Fe–Mn layer depends on the applied potential during the deposition. The structural and magnetic characteristics of the obtained films were investigated. The set of results shows the Fe–Mn layer presents this antiferromagnetic phase which leads to exchange bias at room temperature and at lower temperatures. The bias fields are small, but, given the simplicity of the method, the results show its potentiality to be employed for the production of spin valves as well as other devices.

铁磁/反铁磁双层被用于许多自旋电子器件中。随着该研究和开发领域及其商业用途的增长，需要更多生产方法的可用性。在这种情况下，电镀可能起着重要的作用，类似于传统微电子学中的电镀。在目前的工作中，FeMn / Ni双层膜是由硫酸盐电解质电沉积的。铜电极用作衬底，以诱导γ-FeMn相的生长。样品经过恒电位沉积，Fe-Mn层的成分取决于沉积过程中施加的电势。研究了所得膜的结构和磁性。结果集表明，Fe-Mn层存在这种反铁磁相，从而导致在室温和较低温度下产生交换偏压。偏置场很小，但是，鉴于该方法的简单性，结果表明其潜力可用于生产旋转阀以及其他设备。
