Enhanced in-plane magnetic anisotropy in thermally treated arrays of Co-Pt nanowires

CoPt Nanowires with Low Pt Content for the Catalytic Methanol Oxidation Reaction (MOR)

“…Metallic materials in the shape of nanowires, nanorods, or nanotubes are used in a wide range of applications in nanomedicine, electronics, and catalysis. The physical properties of nanostructured materials are different from the properties of the same materials in bulk or single-crystal shape, being strongly dependent on the particle size and geometry. − The change in properties is due to the increase in the surface to volume ratio, , the particular shape of the nanostructured materials, the aspect ratio of the nanostructure, and the synthesis conditions. , …”

“…One of the challenges for nanomaterial synthesis by chemical routes is the preparation of particles having homogeneous size and shape. Conveniently, electrodeposition inside the nanopores of anodic aluminun oxide (AAO) templates allows an excellent control of the nanowires’ shape, dimension, and aspect ratio. ,, …”

Improvement of the Electrocatalytic Properties for the Methanol Oxidation Reaction (MOR) of the CoPt Alloy

“…The Co is also known as an oxophilic metal in the binary catalysts and has the advantage of being a cheap metal, leading to a decrease in the catalyst price. The CoPt alloys can be synthesized by several routes, among which we can mention the chemical reduction, electrochemical deposition or micellar technique [26][27][28][29][30][31].…”

Towards three-dimensional nanoarchitectures: highly ordered bi-layer assembly of tailored magnetic nanowire arrays via template-assisted electrodeposition

“…12 In this sense, magnetic NW arrays are thought to be good candidates for information storage devices as the magnetic anisotropies and the template's geometrical parameters can tune the coercivity, SQ, and magnetization dynamics of the bulk sample. [13][14][15][16] Moreover, with the increasing demand in miniaturization and the physical limitation of 2D scaling dictated by Moore's law, [17][18][19] various applications in nanotechnology with 3D architecture have been demonstrated using top-down lithography and bottom-up self-organization. [20][21][22][23] In the realm of template assisted electrodeposition, NWs such as FeCoCu NWs with modulated diameters, 24 FeGa/Cu multisegmented NWs, 25 and CoFe 2.7 / CoFe 2 O 4 alloy core/shell NWs 26 have been fabricated for their complex magnetization configurations based on vortex structures, antiferromagnetic intersegment/ferromagnetic interwire ordering, and superexchange/direct exchange interactions, respectively.…”
