Abstract

Fe-B alloy films were fabricated by an electrochemical deposition method. The effects of deposition parameters including current density, solution concentration, and ratio of precursors on crystallinity and magnetostrictivity were investigated. Amorphous Fe-B alloy films were obtained in the conditions of effective boron incorporation and high nucleation rate by increasing current density, solution concentration, and ratio of iron precursor. The results indicate that amorphous phase formation is related to deposition kinetics and chemical affinity between iron and boron precursors. The magnetostrictive characterization of the deposited amorphous Fe-B alloys demonstrated a potential biosensor platform of the films.
