Popis: The electrochemical synthesis of Ni-Co metal particles formed from through electrodeposition of Ni2+ and Co2+ was carried out from a deep eutectic solvent of choline chloride and urea in 1:2 molar ratio at 70 °C, as electrolytic medium. From the application of a constant external magnetic field (1-5 µT), the morphology of the particles formed was studied. Additionally, the kinetic and thermodynamic parameters corresponding to the formation of the new phase on the surface of the glassy carbon electrode was determined, using physicomathematical models that involve bimetallic phases [1]. Figure 1(a) and (b), show the SEM images displaying a noticeable change in the morphology after applying 5 µT. Figure (c) and (d), correspond to the elementary analysis of figures (a) and (b), respectively. Figure 1
