“…Such interactions increase when the diameter of the nanowires, and thus the saturation magnetization, increases despite the reduction of the distance between them. Avoiding any contribution from magnetocrystalline anisotropy, ensuring that each nanowire can be a single magnetic domain, makes this system of special interest when studying the magnetic interactions in nanowire arrays for their application in high-density magnetic storage technologies (Nielsch et al, 2001(Nielsch et al, , 2002Vázquez et al, 2004aVázquez et al, ,b, 2005Samardak et al, 2012).…”

“…The combination of this unique structure with uncommon magnetic, optical and transport properties can be used to develop novel functional nanomaterials for magnetic, electronic, biomedical and optical nano-scale devices [1–5]. Additionally, the magnetic composite nanostructures are interesting as materials for basic research of magnetic and transport properties in magnetic nanosystems as they possess unique physicochemical properties compared with thin-film and bulk analogues [6–7].…”

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.

“…For this reason, magnetic nanowires (NWs) of different materials were investigated [3]- [5]. NWs are particularly attractive due to their pronounced shape anisotropy, which orients the magnetic moments along the NW's longitudinal axes, forming a high-density perpendicular magnetic recording medium with small switching fields and a high thermal stability [4]. An array of such nanomagnets could lead to an ultrahigh storage density of 1 Tbit/in 2 [6].…”

Using electrodeposition into anodic aluminum oxide (AAO) membranes, we have successfully fabricated near-equiatomic Fe 48±3 Pd 52±3 nanowires (NWs) with the diameter of ≈200 nm and the length of ≈3.5 µm. X-ray diffraction and transmission electron microscopy/selected-area electron diffraction analyses revealed that the as-deposited NWs are isotropic and polycrystalline with an average crystal size of 5 nm and have an fcc crystal structure. Magnetic force microscopy (MFM) on a single Fe-Pd NW revealed its single-domain behavior with the easy axis of magnetization along the long axis of the NW. The magnetizationswitching behavior of a single Fe-Pd NW studied with the MFM suggested a square-shaped magnetization curve (M/M s = 1) with H C ≈ 3.2 kA/m. In addition, using in-field MFM techniques, the effects of dipolar interactions in an Fe-Pd array of NWs still embedded in the AAO were determined. It was found that the dipolar interactions greatly reduce the parameters of the magnetization hysteresis loop, such as the coercivity, the remanence, and the switching-field distribution of the Fe-Pd NW array.Index Terms-Easy axis, Fe-Pd alloy nanowires (NWs), magnetic NWs, magnetostatic interactions, shape anisotropy.
