Study on the pulse electrodeposition of La–Ni–Co alloy from dimethylsulfoxide
چکیده انگلیسی

The conductivity of research salts has been studied in dimethylsulfoxide (DMSO) at 298 K. The experimental results indicate that La(ClO4)3 has strong electrolyte property in DMSO. Cyclic voltammetry is used to investigate the electrochemical behavior of La3+ ion in the 2.5 × 10− 3 mol L− 1 La(ClO4)3–7.5 × 10− 2 mol L− 1 LiClO4-DMSO system on a Pt electrode. Some electrochemical parameters indicate that the reduction of La3+ ion is irreversible. The pulse deposition technique is used to prepare La–Ni–Co alloy films. The surfaces of La–Ni–Co alloy films are uniform, adhesive, compact and showed a metallic luster. The grain sizes of La–Ni–Co alloy observed by scanning electron microscope (SEM) are nanometer or submicron degree. La–Ni–Co alloy film is amorphous as proven by the X-ray diffraction (XRD). The magnetic properties of the amorphous La–Ni–Co alloy film are measured. The saturated magnetization intensity (Ms), coercive force (Hc) and remanence (Br) are 23.53 emu g− 1, 214 Oe and 11.68 emu g− 1, respectively.
