چکیده مقاله
Fe49Co33Ni18 nanowire arrays (175 nm in diameter and lengths
ranging from 5 to 32μm) were fabricated into nanopores of
hard-anodized aluminum oxide templates using pulsed ac
electrodeposition technique. Hysteresis loop measurements
indicated that increasing the length decreases coercivity and
squareness values (from 274 Oe and 0.58 to200 Oe and 0.105,
respectively), indicating the increase in magnetostatic
interactions between the nanowires (NWs).On the other hand,
first-order reversal curve measurements showed a linear
correlation between the magnetostatic interactions and length
of NWs. It was also found that with increasing length, the
domain structure of NWs changed from single-domain to
pseudo single-domain state. A multidomain-like behavior is
also seen for the longest NWs length.Increasing the length of
NWs resulted in an increase inthe interaction and decrease in
the array coercive field(H
