FeCo nanowires 20 nm diameter are synthesized by AC electrodeposition using AAO membranes as templates. The hysteresis and structural properties of the as deposited nanowire arrays are characterized. The orientation dependence of the coercive field measured in the array is compared with the predictions of a magnetization reversalmodel involving the nucleation and propagation of a transverse wall. The model is promissory because it predicts the experimental curve shape quite well.
