Abstract

100 keV Nitrogen implantation reduced initial magnetic permeability and increased coercive force in crystalline nickel wires (d=0.5 mm) and amorphous Fe₈₅B₁₅ metallic glass ribbons (~40 μm thick). Permeability was measured with Maxwell bridge and coercive force with Kerr magnetooptical hysteresis graph. The bulk permeability of crystalline nickel wires showed a 14% reduction. In amorphous samples due to the smaller range of implanted ions (~110 nm, for lack of focusing and channelling-effect) only the Kerr-method was sensitive enough to show the maximum 30 times multiplied surface coercivity. Unchanged bulk properties in Fe₈₅B₁₅ is attributed to the surface irregularities present already before implantation too
