“…Indeed, the application of a magnetic field in the electro-deposition yields chiral patterns of either clockwise or anticlockwise handedness, depending on the magnetic field orientation with respect to the electrode surface [20]. The inhomogeneity due to the confinement of the electrode and the size of the magnet could generate vortexes all around the electrode, and even smaller vortices on the electrodeposited asperities [21]. For this reason, even when the current and magnetic field are nominally parallel, numerous works have found that the inherent inhomogeneity (e.g., edge effects) of electrodes and magnets can lead to local variations in both current and magnetic field, resulting in significant and complex convective flows [16].…”

Magneto-electrochemistry (MEC) experiments were carried out in the electrodeposition of a ferromagnetic Heusler alloy. The electrodeposition was carried out in the absence (as a reference) and in the presence of a magnetic field that was applied perpendicularly to the electrode–solution interface. The obtained metallic deposit was characterized by SEM-EDS, XRF, and XRD techniques. The ferromagnetic properties are assessed on the basis of SQUID measurements. The experimental results indicate that the influence of the presence of the magnetic field induces differences in the electrochemical measurements and a macroscopic handedness (chirality) in the deposit, which is a function of magnet orientation. Eventually, the coercivity of the Heusler alloy that was obtained in the presence of the magnetic field was larger compared to that of the deposit that was obtained without a magnetic field.

“…When strong magnetic field gradients ∇B ≈ 100 T m −1 and paramagnetic species are present in the solution, the Lorentz force is insignificant and the Kelvin force becomes dominant when a gradient of paramagnetic ions is established. The classical and much studied example in which paramagnetic ions can be influenced by the Kelvin force is the electrodeposition of copper [145][146][147][148][149][150][151][152][153][154][155][156][157]. A one-molar aqueous solution of Cu 2+ has χ = 7 × 10 −6 [57].…”

An overview of the effect of a magnetic field gradient on fluids with linear magnetic susceptibilities is given. It is shown that two commonly encountered expressions, the magnetic field gradient force and the concentration gradient force, for paramagnetic species in solution are equivalent for incompressible fluids. The magnetic field gradient and concentration gradient forces are approximations of the Kelvin force and Korteweg-Helmholtz force densities, respectively. The criterion for the appearance of magnetically induced convection is derived. Experimental work in which magnetically induced convection plays a role is reviewed.

“…In recent years, electrodeposition technique has been extensively developed for the realization of microstructures [7][8][9] and nanostructures [10][11] using patterned electrodes, pulse conditions or magnetohydrodynamic effects [12][13][14][15][16][17]. These techniques allow the growth and fabrication of planar or three-dimensional micrometer-scale and nanometer-scale structures without the necessity for lithography process.…”

The influence of different anode configurations on the growth mechanisms, transient currentsand surface morphologies of copper film using localized electrodeposition technique have been studied. Measured transient currents during electrodeposition wereused to investigate the underlying growth dynamics. SEM images were obtained and the surface morphologies of the deposited copper films were analyzed. It was found that the transient current increased when copper ions were able to grow directly on the empty surface of the copper film that was located away from the mini electrodes. This caused the copper ions to be deposited sporadically via the instantaneous growth mechanism and formed cluster of atoms on the empty surface of the copper film which led to rougher surfaces. In contrast, progressive growth was observed to occur at a faster rate for thedeposition performed using insulated mini electrodes, especially in the case of collinear double insulated mini electrodes as indicated by the reduction of the transient current with time. Besides, copper films with uniform and smoother surfaces were obtained when the depositions were performed using multiple or a large number of closely spaced mini electrodes. This was due to the fact that large number of closely spaced mini electrodes produced parallel and uniform electric field patterns.
