“…The preparation processes include template-free methods [1–3] and template-based methods [4–7]. The template-based method using nanochannel structures such as ion track-etched foils or aluminum oxide membranes [8] is a promising technique to achieve precise length and diameter scales.…”

Textured ferromagnetic Fe nanowire arrays were electrodeposited using a rectangular-pulsed potential deposition technique into anodized aluminum oxide nanochannels. During the electrodeposition of Fe nanowire arrays at a cathodic potential of − 1.2 V, the growth rate of the nanowires was ca. 200 nm s−1. The aspect ratio of Fe nanowires with a diameter of 30 ± 5 nm reached ca. 2000. The long axis of Fe nanowires corresponded with the <200> direction when a large overpotential during the on-time pulse was applied, whereas it orientated to the <110> direction under the potentiostatic condition with a small overpotential. By shifting the on-time cathode potential up to − 1.8 V, the texture coefficient for the (200) plane, TC200, reached up to 1.94. Perpendicular magnetization performance was observed in Fe nanowire arrays. With increasing TC200, the squareness of Fe nanowire arrays increased up to 0.95 with the coercivity maintained at 1.4 kOe at room temperature. This research result has opened a novel possibility of Fe nanowire arrays that can be applied for a new permanent magnetic material without rare-earth metals.

In the present work, the stable atom-scale iron quantum wire was electrochemically prepared and characterized successfully by a homemade electrochemically controlled system. By adjusting the resistance of the external resistor, the atom-scale iron wire with preset conductance would be obtained. When scanned with low bias, the iron quantum wires showed the linear ohmic relationship for the current-voltage curve. With an external resistor control, the diameter, aspect ratio can be easily tailored, so it was a simple and controllable method. In addition, with a pure water environment of the preparation, the method had a less interference of other ions and was more suitable for sensor study of the quantum wire. The work was greatly significant for material science, molecular electronics, chemical and biological sensing.
