“…In contrast, both the current efficiency and the Fe content show almost constant values except for 0 g/L of NH4Cl, indicating that we can vary the concentration of NH 4 Cl without the change in the Fe content. The current efficiency of approximately 95% is much higher than those for our previous study (85%) [5] and other researcher's ones (60 -80%) [10][11]. Fig.2.…”

We electroplated Fe-Ni films in plating baths with ammonium chloride (NH4Cl) and evaluated the magnetic properties of the films. The amount of NH4Cl did not affect the current efficiency of the plating process and the Fe content in the film. The obtained current efficiency of approximately 95% is much higher than our previous study. The coercivity dramatically decreased with increasing NH4Cl from 0 to 15 g/L, and we obtained Fe22Ni78 films with very low coercivity (10 A/m). The Cl -concentration in the plating bath affected the coercivity, and we found that a plating bath with moderate low concentration of Cl -is preferred for obtaining the Fe22Ni78 films with low coercivity.

“…[8][9][10] When considering the mass production of the soft magnetic thick films for applications as described above, the current efficiency as well as the good soft magnetic properties is one of important factors since the high efficiency enables us to obtain the films in short plating time. Although many plated Fe-Ni films with good soft magnetic properties have been reported, the efficiency are relatively low (60-70%) 11,12 compared to that for plated Ni films (>95%). 13 Recently, we have reported the Fe-Ni films with good soft magnetic properties prepared in a citric-acid-based plating bath.…”

Fe-Ni films were electroplated in a citric-acid-based plating bath, focusing on the current efficiency of the plating process. We prepared the plating baths with various citric acid contents, and evaluated the magnetic properties of the films and the current efficiency. The film with Fe content of approximately 22 at. % was obtained by adjusting the iron sulfate content in the plating bath, and we found that the Fe-Ni films with low coercivity (<30 A/m) could be obtained in the baths with various citric acid contents. For the current efficiency, we found that the baths with low citric acid content are effective to obtain high efficiency. The bath with the citric acid content of 10 g/l showed high current efficiency (85%), and the high efficiency enables us to increase the plating rate. The maximum plating rate was 186 lm/h, and we obtained 1.3 times higher rate compared to that for our previous study. Therefore, we concluded that the bath with low citric acid content is a suitable plating bath to obtain thick Fe-Ni films in a short time. V C 2015 AIP Publishing LLC.

“…The increasing tendency of the current efficiency almost agrees with the results for the bath containing the boric acid. 18,19 From these results, we found that a high current density is effective to obtain the film with low coercivity and high current efficiency.…”

In order to improve soft magnetic properties of electrodeposited Fe-Ni films prepared in a citricacid-based bath, we investigated the effect of the current density on the grain size and the coercivity of Fe 22 Ni 78 and Fe 35 Ni 65 films. Consequently, we confirmed that increase in a current density reduces the coercivity and the grain size. This result suggests the exchange softening effect works effectively by the reduction in the grain size. We confirmed that the increase in the current density is effective to improve in soft magnetic properties of Fe-Ni films electrodeposited in the citric-acid-based bath. V C 2014 AIP Publishing LLC.
