“…4a), while at higher potentials (−1.1 V and −1.2 V) we observed a smaller coercive field being 230 Oe and 220 Oe, respectively. The decrease in the value of the coercive field along with the increase in the potential of wire deposition was also observed by other studies [1,6,17]. For the sample deposited at −1.0 V, independently of applied magnetization direction, the same value of coercivity H c = 344 Oe was observed.…”

“…The easy magnetization direction is oriented along the wire axis. In other studies, it has been reported that an increase of the cathodic potential can enhance effective anisotropy and coercivity along nanowires [14,17], as well as acting in the opposite way [6,17].…”

“…Membrane parameters, electrodeposition parameters, selection of metal as well as membrane preparation strongly affect the nanowire properties. Many studies have been performed to determine the magnetic properties of metal nanowires [6][7][8]. The studies show both an increase [9,10] and a reduction [11,12] of coercivity value with a decrease in nanowire diameter and length occurred with an easy axis of magnetization along nanowires.…”

The iron nanowire arrays (NWs) were fabricated by DC electrodeposition into hexagonally ordered alumina pores. With the use of X-ray diffraction analysis, the structure of iron wires was determined. The iron wires have the Body Centered Cubic structure. The influence of cathodic deposition potential and parameters of membrane on the magnetic properties of nanowire arrays was investigated. Magnetic properties analyzed by VSM measurements suggest that the easy axis of magnetization follows the nanowire axis, with coercivity increasing with a decrease of nanowire diameter and length. The dependence of the height of Fe wires on the electrodeposition potential was determined. The low cathodic potential and smaller pore diameter are the synthesis parameters most beneficial for large coercivity with easy axis along nanowires.

“…Such influence of Cu atoms was reported in [3] and was also seen in, synthesized by us, Fe nanowires doped by Cu atoms (paper in preparation). All analyzed nanowires possessed caps, which strongly influenced magnetic behavior, favoring in plane orientation of magnetic easy axis, when continuous layer is reached [1]. In our case, caps separated from one another should rather give contribution to isotropic magnetic arrangement.…”

“…A special attention in recent investigations is focused on one-dimensional magnetic nanostructures such as nanowires. The control of geometrical parameters of nanowires and their structure determined by process parameters, allows one to tune the magnetic properties [1,2], offering a variety of applications from high density magnetic recording media to high quality sensors and microwave devices [3]. The magnetic multilayered nanowires composed of alternatively aligned magnetic and non-magnetic layers represent an important family of materials attractive for GMR sensor applications [4,5].…”

We studied changes of morphology and magnetic properties of Co/Cu multilayered nanowires, electrodeposited in polycarbonate membranes, as a function of Cu layer thickness. The morphology and structure of wire assemblies with an average diameter of 200 nm and length of 10 µm, investigated by X-ray diffraction and scanning electron microscopy techniques, revealed polycrystalline structure of Cu and Co layers with smooth lateral surface of nanowires. Overdeposited nanowires created caps which showed flower-like dendrites with shape changing as a function of Cu thickness and electrodeposition parameters. Chemical composition of Co and Cu nanowires analysed by energy dispersive spectroscopy and proton induced X-ray emission showed Cu nanowires free from Co atoms while in Co nanowires, Cu contamination with concentration below 10% was observed. The oxidation traces observed in single-component Cu nanowires did not appear in multilayered nanowires. Magnetic measurements indicated easy axis of magnetization in membrane plane for nanowires with Cu thickness smaller than 20 nm, whereas for larger Cu thicknesses isotropic orientation of magnetization was observed. The presence of Cu atoms in single-component Co nanowires resulted in the appearance of magnetic anisotropy with easy axis along nanowire axis and the increase of coercivity value.
