Magnetic nanoparticles and magnetic nano-species of complex topology (e.g., nanorods, nanowires, nanotubes, etc.) are overviewed briefly in the paper, mostly giving attention to the synthetic details and particle composition (e.g., core-shell structures made of different materials). Some aspects related to applications of magnetic nano-species are briefly discussed. While not being a comprehensive review, the paper offers a large collection of references, particularly useful for newcomers in the research area.

“…Further studies showed that nanowires can be formed in much simpler systems: between a pair of vibrating wires (1995) [16] and between relay contacts (1997) [17]. There have also been attempts to produce metallic nanowires by electrochemical methods, including the use of porous molds and nanolithographic methods [18][19][20][21][22]. Some interesting information about the formation of Pt nanowires by atomic layer deposition on highly ordered pyrolytic graphite can be found in the literature [23].…”

Abstract:The following paper presents the possibility of formation of Pt nanowires, achieved by a three-step method consisting of conformal deposition of a carbon nanotube and conformal coverage with platinum by physical vapour deposition, followed by removal of the carbonaceous template. The characterization of this new nanostructure was carried out through scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray di raction (XRD).

AbstractIn this work we have studied the magnetic properties of a system formed by a Nb thin film deposited on top of an array of ferromagnetic Ni nanowires embedded in a ordered porous alumina membrane as substrate. The substrates were obtained by the two-step anodization technique, followed by an electrodeposition AC of the ferromagnetic material. The Nb film was deposited via magnetron sputtering. The magnetic response of this system was investigated over a wide range of temperatures through AC susceptibility, DC magnetization and magneto-optical images (MOI) measurements.Initially, the magnetic properties of Ni nanowire system were studied. We perform magnetization measurements above the superconducting transition temperature of Nb, in the range of 10 to 300 K where the superconducting film does not contribute to magnetization. These results showed the strong uniaxial character of the effective anisotropy in such systems, as well as its dependence on the temperature and t...
