Magnetostatic interaction in FeCo nanowire arrays

FexCo1-x alloy nanowire arrays are deposited by a dc electrochemical method with anodic aluminum oxide nanoporous templates. Effects of nanowire magnetic moment and interwire distance on the interwire magnetostatic interaction are studied in this paper. It is found that the interaction increases with increase of nanowire magnetic moment and/or decrease of interwire distance. An effective wire diameter is introduced to quantitatively analyze such inetraction. A Monte Carlo simulation is also carried out to calculate the experimental measurements.
