Abstract

Thick films of the Ni₁₁Co₁₁Fe₆₆Zr₇B₄Cu composition were synthesized via screen printing of the ball-milled ribbons of the above composition for possible use as planar inductors. The ribbons were obtained by rapid solidification. The resulting ribbon samples were annealed at 300 degrees C for 2 h to cause embrittlement. They were found to have soft magnetic properties (4πMs∽13 kG,ΔH ∽100 Oe, and Hc< 0.5 Oe). The brittle ribbons were ball milled using tungsten carbide vials and stainless steel balls in an inert atmosphere for various milling times. The sample milled for 10 h was found to have a 4πMs of about 13 kG and a coercivity of about 73 Oe with an average particle size of about 5μm. The screen printed (as prepared and aligned) samples showed a linewidth (Δ H) of about 1000 Oe. Similar values were obtained for screen printed films annealed for 1 h at 200 and 400 degrees C.
