Resum:	An electrochemical synthesis route for NiMnGa alloys is presented. Thin films (TFs) of NiMnGa were fabricated by single step electrodeposition from aqueous electrolytes using direct current (DC) over a range of current densities. By meticulous electrolyte tuning, homogeneous TFs with high Ga and Mn content could be achieved at current densities as high as -400 mA cm-2. Detailed compositional analysis of the alloys showed that growth was homogeneous and oxygen content was minimized. TFs plated at very low current densities were found to be nanocrystalline/ amorphous. In order to obtain fully crystalline samples, thermal annealing was carried out. Mechanical characterization was assessed by nanoindentation, and the effect of Ga content on mechanical properties was investigated.
