Meniscus-confined electrodeposition (MCED) is an effective and versatile technique for fabrication of alloy structures with precise localization and high controllability. Here, the fabrication of cobalt-copper (Co/Cu) alloy microwires using MCED techniques is reported. Co/Cu microwires with a wide range of compositions (Co9Cu91 to Co100Cu0) and controllable morphology were printed using the co-electrodeposition mode from a single electrolyte. We utilized multiphysics finite element simulation to investigate the influence of electrolyte evaporation and electric field on the concentration distribution of metal ions in the meniscus. The concentration of ions at the substrate interface increases linearly with decreasing humidity and increasing current density, which can be used to fine turn the alloy composition. By further analyzing the alloy composition, we found that the electrodeposition of Cu is diffusion controlled, while Co is mainly electrochemical reaction controlled, as a results of combined action of surface evaporation and reaction dynamics in the meniscus. The prepared alloy wires are polycrystalline, dense and uniform composition distribution. The coercivity and magnetic anisotropy are enhanced by increasing of the copper content in the alloy wires. The high tunability of composition make this alloy a promising material for magnetic micro/nano-electromechanical devices.

“…Development and study of new magnetic films is one of the most important problems of modern nanotechnology and nanoelectronics. granular metallic solids have attracted much attention due to the discovery of giant magnetoresistance, enhanced coercivity (Hc), extraordinary Hall effect, giant magnetothermal properties, and other enhanced properties [1,2]. The magnetic granular films, in which magnetic (Co, Ni, Fe, Py) particles are embedded in the non-magnetic matrix (Ag, Cu, Au), display a giant magnetoresistance effect.…”

“…The magnetic granular films, in which magnetic (Co, Ni, Fe, Py) particles are embedded in the non-magnetic matrix (Ag, Cu, Au), display a giant magnetoresistance effect. Magnetic atoms located at the interfaces between the magnetic clusters and the non-magnetic matrix play an important role in magnetoresistance [1][2][3][4]. magnetic granular alloys have found a wide range of applications in nanoelectronics (e.g.…”

Co-Ag granular films were prepared by electrodeposition method. The influence of the composition of thin films on their structure, granular size and magneic properties is presented. structural techniques (XRD and TEM) confirmed the heterogeneity of the deposits with a size distribution from superparamagnetic to ferromagnetic particles. Fcc-Ag and Fcc-Co were present in the coatings. The increase of the Co concentration in the film alloys leads to an increase in the size of magnetic granules and a simultaneous decrease of the distance between them. The in-plane easy magnetization axis is found for all samples. Using these results, we computed the first, second magnetic anisotropy factors. Values of the computed effective magnetic anisotropy factors higher than 0.53×10 6 erg/cm 3 have been found.
