“…It was noted that the applied magnetic field strength was too high during the electrodeposition process, and therefore, the deposit tended to form dendritic crystalline structures. 24 This was because the restricted diffusion of cations made the ion concentration on the cathode surface too low, which inhibited further grain growth.…”

“…These excellent properties have brought interesting potential applications for magnetic read heads and sensors. Generally, Co-Cu granular films could be obtained by the application of various techniques, such as magnetron sputtering, molecular beam epitaxy, ion-beam sputtering and electrodeposition [7][8][9][10][11][12][13][14][15][16]. Among them, electrodeposition has been regarded as a successful one to produce films with practical technological applications due to its advantages of cost effectiveness, ease of processability, large area deposition and relatively low temperature [17].…”

A detailed electrodeposition of Co-Cu nanometric granular alloy films in citrate solution has been performed based on a galvanostatic technique. Electrochemical behaviour of the bath solution containing both Co 2+ and Cu 2+ was investigated by linear sweep voltammetry. Cathodic polarization curves indicated that high quality Co-Cu nanometric granular alloy films can be obtained at room temperature with a pH of 6 and current density equal to or more negative than − 1.0 mA cm −2. Magnetic properties of the films were measured at room temperature by the physical property measurement system. Magnetization curves of the as-prepared Co-Cu nanometric granular alloy films displayed superparamagnetism (SPM). However, after annealing at 450 • C for 1 h, magnetic property of the films changed from SPM to ferromagnetism. Meanwhile, the annealed Co-Cu nanometric granular alloy films showed an increase in saturation magnetization with the increase of the current density.

“…During the growth progress of the films, the nucleation, particle diffusion, crystal growth and orientation of the films are affected by HMFs without contact and without changing the preparation conditions and the environment of the films. Thus, the texture, grain size and distribution, growth structure and phase transition of the films have been tuned. Meanwhile, the magnetic and electrical properties of the films have been improved by HMFs .…”

To realize the application of Ni films in magnetic recording media, giant magnetoresistive sensors and microelectromechanical systems, it is necessary to control and improve the magnetic and electrical properties of the films. In this paper, Ni nanocrystalline films with different thicknesses and growth rates are prepared with or without a high magnetic field (HMF). The effects of a HMF on the growth, magnetic and electrical properties of the Ni films are studied. The results show that HMF changes the growth structure of the Ni films from disordered stacked grains to columnar growth along the direction of the HMF. The columnar growth becomes more prominent at a high growth rate and large film thickness. The HMF increases the grain size but decreases the surface roughness of the Ni films. Due to changes in the growth structure, grain size and film quality, the saturation magnetization of the Ni films increase markedly (by 89%), and the resistivity and coercivity significantly decrease (by 89 and 58%, respectively) by the HMF. The remanence ratio of the Ni films is controlled by the HMF. This study shows that a HMF effectively controls the growth and improves the magnetic and electrical properties of Ni films.
