Title
Research Papers / Electrometallurgy : Microstructure and Magnetic Properties of Co(P) Alloys Electrodeposited from Ammoniacal Solutions
이관희Kwan Hyi Lee,김긍호Gyeung Ho Kim,정원용Won Young Jeung
Abstract
The variation of magnetic properties of electrodeposited thin film Co(P) alloys was studied using a different concentration of ammonium chloride in the solution. Using cyclic voltammetry as an electro-analytical technique, change in cathodic polarization behavior was measured. It was speculated that the kinetics of nucleation and electrocrystallization process of Co(P) alloys was modified by the concentration of ammonium chloride. The addition of ammonium chloride seems to suppress the polarization and kinetics of electrocrystallization by charge tranfer leading to a larger grain size and highly preferred orientation. Such microstructural features were confirmed by imaging and electron diffraction method in the TEM.
