Co89Cu11 nanowire arrays with particular bunchy shape have been fabricated in anodic aluminum oxide templates by electrodeposition. The analysis of structure indicates that the bunchy shape of the nanowire actually is a very high concentration of stacking faults parallel to the wire. Then we give explanation to the structure according to the growth mechanism. Relatively high squareness parallel to the nanowire arrays of about 096 at room temperature were achieved owing to the larger shape anisotropy than the nanowire arrays with general structure. The results of magnetic measurement and calculation demonstrate that the symmetric fanning mechanism of sphere-chains model can be employed to explain the magnetization reversal process which rest with the structure of the Co89Cu11 nanowire arrays.
