“…It is well known that ternary ferromagnetic alloy films are interesting soft magnetic materials due to their high saturation magnetization and low coercive field [4,6]. The conducted studies showed that the Fe, Ni, and Co components in binary Ni-Co, Ni-Fe and Fe-Cu and ternary Ni-Co-Cu, Ni-Fe-Cu, Co-Fe-Cu and Fe-Co-Ni magnetic materials grew by the electrochemical deposition technique on Indium Tin Oxide (ITO) covered glass substrates which can be tuned by controlling the Fe, Ni and Co ion concentrations in the Plating Solutions (PSs), respectively [13][14][15][16][17][18][19][20][21]. However, the relative compositions of Co and Fe components in the samples were found be higher than those in the PSs for different electroplating parameters [6,13,14,[16][17][18][19][20][21][22][23][24], which is in good agreement with the definition defined by Brenner [25].…”

In this study, to explore the effect of Co contents on the electroplated Fe–Co–Ni samples, three different Fe–Co33–Ni62, Fe–Co43–Ni53, and Fe–Co61–Ni36 samples were electrochemically grown from Plating Solutions (PSs) containing different amounts of Co ions on indium tin oxide substrates. Compositional analysis showed that an increase in the Co ion concentration in the PS gives rise to an increment in the weight fraction of Co in the sample. In all samples, the co–deposition characteristic was described as anomalous. The samples exhibited a predominant reflection from the (111) plane of the face–centered cubic structure. However, the Fe–Co61–Ni36 sample also had a weak reflection from the (100) plane of the hexagonal close–packed structure of Co. An enhancement in the Co contents caused a strong decrement in the crystallinity, resulting in a decrease in the size of the crystallites. The Fe–Co33–Ni62 sample exhibited a more compact surface structure comprising only cauliflower–like agglomerates, while the Fe–Co43–Ni53 and Fe–Co61–Ni36 samples had a surface structure consisting of both pyramidal particles and cauliflower–like agglomerates. The results also revealed that different Co contents play an important role in the surface roughness parameters. From the magnetic analysis of the samples, it was understood that the Fe–Co61–Ni36 sample has a higher coercive field and magnetic squareness ratio than the Fe–Co43–Ni53 and Fe–Co33–Ni62 samples. The differences observed in the magnetic characteristics of the samples were attributed to the changes revealed in their phase structure and surface roughness parameters. The obtained results are the basis for the fabrication of future magnetic devices.

Electrochemically fabricated ternary Fe-Co-Ni alloy thin films with different chemical compositions were obtained at different deposition potentials. An increase in the deposition potential increased the Ni content while it decreased the Co and Fe contents in the film structure. An anomalous co-deposition behaviour was also studied and the anomalous order of co-deposition was found to be Fe-Ni > Co-Ni > Fe-Co irrespective of deposition potential. Structural characterizations confirmed the presence of single face-centred cubic (fcc) phase structure with [111] preferred crystallographic orientation for all films. The size of the crystallites and the texture degree increased with increasing applied deposition potential. Smaller globular particles occurred on the surface structure of the film fabricated at higher deposition potentials compared to those grown at lower deposition potentials. A decrement detected in the coercive field with increasing applied deposition potential was related to the variations occurred in the chemical composition and the particle size. Keywords Ternary Fe-Co-Ni thin films • Morphologies • Magnetic features • Texture degree • Anomalous co-deposition • Applied deposition potential This paper was presented at ICSM 2018.
