Abstract
In this study, the effect of ammonium chloride on the electrodeposition of CoP magnetic alloy film was investigated. The correlation between the electrodeposition condition and the magnetic properties was tried to elucidate by the electro- analytical tests such as cyclic voltammetry. It was observed that the magnetic properties of the films were varied extensively with the ammonium chloride contents in the solution. The reason why the magnetic properties of the films were varied with the addition of ammonium chloride was thought that the addition of ammonium chloride controlled the electrocrystallization of CoP kinetically by charge transfer and increased the grain size and the orientation factor. This may cause the variation of the magnetic properties of CoP films.
