A facile and efficient synthesis route for the preparation of high entropy Nd-Fe-Co-Ni-Mn alloy films was reported.Here the films with nanostructures were successfully synthesized by electrodeposition at room temperature.By changing the electrodeposition parameters,such as the deposition potential and deposition time,the styles of the nanostructures and surface morphologies of the deposits can be well controlled.The SEM images show that the surfaces of the films,prepared at-2.2 V on Ti substrates for 5 min,are composed of great deal of close-grained and homogeneous nanoparticles with size about 200 nm.The film will become more compact with a longer deposition time.When the deposition potential was shifted negatively without changing other conditions,nanosheets can be successfully prepared.The EDS indicates that the five elements are co-deposited.We conclude a typical induced codeposition of Nd and the transition elements does occur in DMSO.The result of XRD suggested that the film was amorphous.The as-deposited alloys show soft magnetic properties.
