High water content type IV-deep eutectic solvents (DES) formed from calcium chloride hexahydrate and ethylene glycol (CaCl₂⋅6H₂O:EG) were investigated for the deposition and co-deposition of Fe, Nd and FeNd. Cyclic voltammetry demonstrated the feasibility of electrodepositing of Fe, Nd and FeNd, despite the DES containing ca. 21.3 mol kg^‒1 water. Diffusion coefficients for the soluble Fe²⁺ and Nd³⁺ species were estimated using the Cottrell equation to be in the order of 10^–7 to 10^–6 cm² s⁻¹ at 40 °C. A coating of pure Fe was observed under insonated conditions.
