“…Research in the field of nanostructure array formation is mostly concentrated on carbon nanotubes (CNT) [11,12] and magnetic or semiconducting nanowires or nanodots [13][14][15]. However, the physical vapor deposition (PVD) [11] and chemical vapor deposition (CVD) [16] methods of their synthesis require high temperatures.…”

“…Applying porous alumina as a template allows forming arrays of vertically ordered NPs with uniform geometrical parameters (diameter, length, and density), which can be readily controlled in a wide range of sizes [32,33]. Additionally, porous alumina is the heat-resistant material that allows carrying out various experiments at high temperatures [34,35]. Furthermore, the TPAA synthesis is simple and inexpensive.…”

The paper discusses the formation of Ta2O5 pillars with Ni tips during thin porous anodic alumina through-mask anodization on Si/SiO2 substrates. The tantalum nanopillars were formed through porous masks in electrolytes of phosphoric and oxalic acid. The Ni tips on the Ta2O5 pillars were formed via vacuum evaporation through the porous mask. The morphology, structure, and magnetic properties at 4.2 and 300 K of the Ta2O5 nanopillars with Ni tips have been studied using scanning electron microscopy, X-ray diffraction, and vibrating sample magnetometry. The main mechanism of the formation of the Ta2O5 pillars during through-mask anodization was revealed. The superparamagnetic behavior of the magnetic hysteresis loop of the Ta2O5 nanopillars with Ni tips was observed. Such nanostructures can be used to develop novel functional nanomaterials for magnetic, electronic, biomedical, and optical nano-scale devices.

The comparative analysis of the electrochemical deposition of Ni and Ni–Fe nanowires (NWs) into ordered porous alumina templates is presented. The method developed allows for obtaining NWs of 50 ± 5 nm in diameter and 25 μm in length, i.e., with an aspect ratio of 500. XRD data demonstrate the polycrystalline nature of Ni and Ni–Fe in a face-centered cubic close-packed lattice. Both fabricated materials, Ni and Ni–Fe, have shown ferromagnetic properties. The specific magnetization value of Ni–Fe NWs in the alumina template is higher than that of the Ni sample and bulk Ni, also the Curie temperature of the Ni–Fe sample (790 K) is higher than that of the Ni sample one or bulk Ni.
