“…This much higher sensitivity against implantation can be attributed to several things: -The average projected penetration ranges (Rp) of 100 keV implanted nitrogen and carbon ions in crystalline nickel are -200 nm and -240 nm respectively (according to a statistical model [6] ). The ranges for the same ions in amorphous Feg5BI5 are -1 10 nm and -130 nm respectively.…”

100 keV Nitrogen implantation reduced initial magnetic permeability and increased coercive force in crystalline nickel wires (d= 0.5 mm) and amorphous Fe,,B,, metallic glass ribbons (-40 pm thick). Permeability was measured with Maxwell br.idge and coercive force with Kerr magnetooptical hysteresisgraph. 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 is attributed to the surface irregularities present already before implantation too.

“…Reversible magnetic permeability of nickel was determined with the help of a 0.4 Alm strong AC (3 kHz) measuring field in a Maxwell bridge [6], whereas the surface coercive force of amorphous ribbons was measured by a Kerr magnetooptical hysteresisgraph, which gives information from a 30-50 nm thin surface layer [7].…”
