The results of an investigation of thin Ni and CoNiMnP films deposited by electroplating over polyurethane-acrylate flexible substrates are presented. To improve magnetic properties of the films, an electroplating process was carried out with assistance of a strong magnetic field (3900G). The evaluated film properties were coercivity, remanence, maximum energy product, adherence and film composition. Comparison between the magnetic properties of the samples has shown that Ni and CoNiMnP films are suitable for distinct areas of applications in micro-devices: vibrating diaphragms and micro-magnet machines, respectively. ► Ni and CoNiMnP films were electroplated in presence of magnetic field. ► Magnetic and mechanical properties of films were evaluated. ► Ni films presented higher remanence and stress resistance. ► CoNiMnP films have higher coercivity and maximum energy product.
