چکیده مقاله
FeCoNi nanowire arrays with 60 nm diameter and lengths ranging from 10 to 18 m were prepared by ac-pulse
electrodeposition into the nanopores of hard anodized aluminum oxide templates. The effect of nanowires length
on the magnetostatic interactions was investigated using first order reversal curve method. The Fe0.50Co0.29Ni0.21
nanowires with different lengths showed interacting single-domain behavior. The coercivity and squareness
enhanced from 603 Oe and 0.486 to 700 Oe and 0.646, showing the decrease in magnetostatic interactions
between the nanowires. It was detected that an increase in wire length results in an increase in the spread of the
distribution in the Hu direction of FORC distribution. This indicates dominant effect of inter-wire magnetostatic
interaction to interior exchange interaction of nanowires.
