Figure 1. (a) Schematic representation of the experimental setup for magneto-electrochemical deposition. CE: counter electrode; WE: working electrode; RE: reference electrode. (b) I−t curve in the process of switching a magnetic field from 0 to 4000 Gs. (c) X-ray absorption near-edge structure spectra of copper deposited with and without a magnetic field, with Cu foil, Cu2O, and CuO serving as reference materials. (d) XRD patterns of Cu films deposited with and without a magnetic field. (e, f) SEM images of Cu films deposited with and without a magnetic field. The insets are digital photos of ITO glasses with deposited Cu layers.
