“…Even though chloride baths are known to generate higher stress than sulfate and sulfamate bath in nickel electrodeposits [35], we previously reported that low-stress Fe-rich FeCoNi thin films can be obtained from chloride baths operating at high temperature [27]. In order to enhance the compatibility of bath to other MEMS processes, the pH of FeCoNi electrolytes was increased to four and L'acsorbic acid was added to improve the stability of bath.…”

“…However, little research has been published about the film stress of FeCoNi electrodeposits. Our group showed that stress could be reduced by increasing the deposition temperature during electrodeposition of iron, Fe-rich FeCo binary alloys, Ferich FeCoNi ternary alloys in additive-free acidic chloride bath [27][28][29]. Tabakovic et al investigated the effects of substrate on FeCoNi electrodeposits [30].…”

“…As a CoFe based ternary alloy, FeCoNi alloy is a widely investigated magnetic material [1,2,[14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. Osaka group studied magnetic properties and other physical properties of electrodeposited FeCoNi alloys [16][17][18][19][20][21][22].…”

“…It was shown 24,25 that mentioned above citrates and ammonia inhibit the kinetics of Fe(II) oxidation to Fe(III), but cannot prevent it. Some attempts were made to prolong bath life by adding reducing agents, [26][27][28] but those compounds can affect the bath maintenance and coatings properties.…”

Electrodeposited Fe-W alloys are the subject of extensive studies to be applied in versatile engineering applications, and many solutions based on Fe(II) complexes are described for their deposition. However, in aqueous solutions containing dissolved oxygen, Fe(II) compounds are unstable thermodynamically and tend to oxidize to Fe(III) state that decreases the sustainability of the baths. The aim of the present study was to develop an environment-friendly and thermodynamically stable Fe(III)-based electrolyte for electrodeposition of Fe-W alloys with tunable composition. It was found that: (i) concurrent use of two complexing agents as citric and glycolic acids stabilizes Fe(III)-based bath in neutral and weak alkaline medium (no precipitates are formed); (ii) the current efficiency of the process can reach up to 60-70%, which has never been reported before for Fe-W alloys electrodeposition; (iii) nanocrystalline Fe-W coatings containing 11-24 at.% of W can be obtained from Fe(III)-based glycolate-citrate bath at temperature range 20-65 • C. The increase in tungsten content in the alloy resulted in decreased grain size up to < 5 nm; (iv) smooth, free of cracks and having deposition rates up to 0.18 μm/cm 1 alloys are successfully electrodeposited at elevated temperatures from elaborated glycolate-citrate electrolyte.

“…[1,2] Fe films have been intensively investigated; several methods have been used to prepare Fe films. [3][4][5][6][7][8][9][10][11][12][13] Among these techniques, the electrodeposition is becoming more and more attractive because it is a relatively simple and low-cost method for the fabrication of magnetic thin films [14] ; it is one of the most promising technologies in industrial level. [2,15] Electrodeposited magnetic thin films of the iron group metals (Fe, Co, and Ni) are being studied because of potential applications in computer read/write heads.…”

Series of Fe films have been prepared by electrodeposition in a solution of iron chloride onto Al substrate. Different deposition times were used in the elaboration process. The texture, the strain, and the grain size values were derived from X-ray diffraction experiments. Scanning electron microscopy (SEM) has been used to get the surface and the cross section images. Vibrating Sample magnetometer has been used to obtain the hysteresis curves; the external magnetic field was applied in different directions in the film plane, and also perpendicular to the film. Hysteresis curves have been obtained at low temperatures [120 K (À153°C) to room temperature]. The h100i texture, small strain, and grain size ranging from 58 to 113 nm are found for these Fe/Al films. All samples show an in-plane magnetic anisotropy, with no preferred orientation within the film plane. Depending on the film thickness range, different mechanisms have been found to be responsible for the coercive field H C behavior. These magnetic properties are correlated with the structural ones and with the SEM observations.
