Magnetic structures with controlled domain wall pattern may be applied as potential building blocks for three-dimensional magnetic memory and logic devices. Using a unique electrochemical self-assembly method, we achieve regular single-crystalline cobalt filament arrays with specific geometric profile and crystallographic orientation, and the magnetic domain configuration can be conveniently tailored. We report for the first time the transition of periodic anti-parallel magnetic domains to a compressed vortex magnetic domains depending on the ratio of height vs. width of the wires. A "phase diagram" is obtained to describe the dependence of the type of magnetic domains and the geometrical profiles of the wires. Magnetoresistance of the filaments demonstrates that the contribution of series of 180 o domain walls is over 0.15% of the zero-field resistance ρ(H = 0). These self-assembled magnetic nanofilaments, with controlled periodic domain patterns, offer an interesting platform to explore domain-wall-based memory and logic devices.

“…In this work, nickel nanowires and nanotubes are fabricated by using template-assisted electrochemical deposition process. Electrochemical deposition is a promising technique for the fabrication of nanostructures in a bottom-up trend and it does not require the employment of complex instrumentation [11][12][13][14].…”

Nickel nanotubes and nanowires are grown by galvanostatic electrodeposition in the pores of 1000, 100, and 15 nm polycarbonate as well as in anodised alumina membranes at a current density of 10 mA cm À2. The effects of pore size, porosity, electrodeposition time, effective current density, and pore aspect ratio are investigated. Nickel nanotube structures are obtained with 1000 nm pore size polycarbonate membrane without any prior treatment method. At the early stages of electrodeposition hollow nickel nanotubes are produced and nanotubes turn into nanowires at longer depositon times. As effective current density accounting for the membrane porosity decreases, the axial growth direction is favoured yielding nanowires rather than nanotubes. However, for smaller pore size polycarbonate membranes, nanowires are obtained even though effective current densities were higher. We believe that when the pore diameter is below a critical size, nanowires grow regardless of current density since narrow pores promote layer by layer growth of nanorods due to smaller surface area of the pore bottom compared to pore walls. Pore size has a dominant effect over effective current density in determining the structure of the fibres produced for small pores. Nickel nanowires are also obtained in the small pores of anodised alumina, which has higher aspect ratios. High aspect ratio membranes favour the fabrication of nanowires regardless of current density.

“…The periodicity on metallic filaments can be controlled by applying external electric pulses, referring to the method in spontaneous formation of periodic nanostructured Cu [15]. Normally, templates can be applied in elecrodeposition to achieve metallic structures with designed pattern, such as paralleled metallic wires [25][26][27]. With these methods, the propagation of surface waves along periodical and corrugated structures could be better controlled.…”

Abstract-Single-crystalline silver filaments with periodic pearlchain-like structures are fabricated by electrodeposition without using any templates, surfactants, and additives. Simulations demonstrate that excited surface waves may sustain on silver pearl chains in middle infrared (Mid-IR) range. The propagation features of surface waves on the silver filaments indicate the structure application for Mid-IR wave transmittance.
