Magnetization reversal studies in structurally tailored cobalt nanowires

Electrochemical synthesis of magnetic nanowires with controlled geometry and magnetic anisotropy

“…By further increasing the Co content, the only stable phase is the g-phase FCC structure with a [110] preferred orientation. Similar data were reported for Co nanowires with diameters between 20 and 30 nm (Cattaneo et al, 2012;Kaur et al, 2013;Yuan et al, 2014). Based on a comparison of Figure 2.16a and b, we can deduce that a small amount of Fe content seems to be enough to promote FCC cubic symmetry (Bran et al, in preparation).…”

Nanoscale characterisation and magnetic properties of Co81Cu19/Cu multilayer nanowires

“…Fig. 3d shows the corresponding EDX spectra measured from the 45 CoCu/Cu, CoCu and Cu nanowires. As expected, Cu peaks are shown in all spectra.…”

“…The average thickness of the Cu modulation is approximately 14 nm, and that of CoCu is for about 132 nm, which are the same as above morphological detections by TEM and STEM. In order to 45 well understand the distributions of two elements within single multilayer nanowire, the mapping images of Co-Kα and Cu-Kα were combined as shown in Fig. 4e.…”

“…The 40 interplanar distances are measured to be 2.05±0.1 Å and 1.81±0.1 Å, well matching with (111) and (200) planes of fcc Cu with [011] orientation. Vegard's law S1 was used to test the relation between the measured lattice constant of the alloy layers and its chemical composition, which calculated an 84.85% Co atomic 45 ratio in Co-rich layers based on the measured lattice constants (see supplementary for details). This value is matched with above experimental data of chemical composition (x=81%) measured by EDX in error, which proves that above chemical analysis and measurements of lattice constants are correct.…”

“…12 Electrodeposition method based on anodised aluminium oxide (AAO) templates or ion-track etched polycarbonate (PC) membranes [13][14][15] is a common technique to prepare magnetic multilayer nanowires. Diverse multilayer nanowires have been 45 synthesized experimentally. 5,[16][17][18][19][20][21][22][23][24][25] Most work focused on their morphological, magnetic and GMR properties.…”
