Abstract
Based on the symmetric fanning mechanism of the sphere-chain model,a systematic study on the hysteresis loops for hexagonal arrays of segmented composite magnetic nanowires fabricated by electrochemical deposition is performed by taking into account the interfacial exchange coupling effect between the segments. The coercivity variation rule with the change of the segments is presented. It is found that the exchange coupling effect between the segments plays an important role for magnetization reversal in the segmented composite nanowire arrays.
