A Deep Eutectic Solvent of 1 chlorine chloride: 2 urea eutectic mixture at 70 °C has been tested as useful to electrodeposit bothmagneticSmCo filmsandnanowires. Galvanostaticdeposition allows obtaining homogeneous deposits over metallic substrate with variable composition as a function of the current density applied. The deposits obtained at 0.5–1.5mA cm−2were uniform and they correspond to a cobalt hexagonal crystalline phase with magnetic anisotropy and coercivity of 250 Oe. It has been possible to deposit SmCo nanowires fromthe DES solvent using alumina templates. Uniform CoSm nanowires of 50 nm of diameter have been obtained; they correspond also to hexagonal phase, but they present higher coercivity

Abstract
A Deep Eutectic Solvent of 1 chlorine chloride: 2 urea eutectic mixture at 70 °C has been tested as useful to electrodeposit bothmagneticSmCo filmsandnanowires. Galvanostaticdeposition allows obtaining homogeneous deposits over metallic substrate with variable composition as a function of the current density applied. The deposits obtained at 0.5–1.5mA cm−2were uniform and they correspond to a cobalt hexagonal crystalline phase with magnetic anisotropy and coercivity of 250 Oe. It has been possible to deposit SmCo nanowires fromthe DES solvent using alumina templates. Uniform CoSm nanowires of 50 nm of diameter have been obtained; they correspond also to hexagonal phase, but they present higher coercivity| File | Dimensione | Formato | |
