Abstract :
CoNi nanowires were deposited by pulsed electrodeposition
technique into porous alumina templates. The effect of off time
between pulses (t
off
) and reductive/oxidative time (t
reduc/oxid
) on the
microstructure and magnetic properties of the CoNi nanowires were
investigated. Maximum coercivity and squareness were obtained for
samples fabricated at t
reduc/oxid
= 0.5 ms and toff
=400 ms. The
coercivity increases in the range of 930–1990Oe by increasing of off
time from 20 to 400 ms. The initially hcp structure of the nanowires
was converted to an amorphous structure by increasing of off time
between the pulses.
