While bulk palladium is non-magnetic, several recent studies have shown that magnetism can occur in hcp Pd films, fcc twinned Pd nanoparticles, and Pd atomic strands. These studies show that small changes in Pd atomic configurations can induce magnetic properties. This raises the question of whether nanoscale Pd structures in general are magnetic. In this work, we examine coaxial palladium nano...

The motion of magnetic nanowires can be manipulated by a magnetic field in liquids so that their distribution, alignment and orientation can be effectively controlled. The small dimensions of nanoscale entities result in an extremely low Reynolds number, and a steady state Stokes flow approximation was adopted to analyze the nanowire motion under the influences of applied field. The effects of ...

In contrast to the majority of related experiments, which are carried out in organic solvents at high temperatures and pressures, cobalt nanowires were synthesized by chemical reduction in aqueous solution with the assistance of polyvinylpyrrolidone (PVP) as surfactant under moderate conditions for the first time, while an external magnetic field of 40 mT was applied. Uniform linear cobalt nano...

Using low-temperature (5 K) spin-polarized scanning tunneling microscopy, we have studied the morphology and magnetic properties of monolayer (ML) and double layer (DL) thick Fe nanowires grown by step flow on a Mo(110) single crystal. Magnetic contrast has been obtained using tungsten tips covered by Au/Co thin films. We find that the DL Fe nanowires, similarly to ML Fe nanowires, are perpendi...

A rapid, template-free method was developed to prepare magnetic, bimetallic Co-Cu nanowires via liquid phase reduction and metal replacement under an external magnetic field. The characterization results confirmed that the as-prepared product was bimetallic Co-Cu nanowires with a desirable linear structure. Additionally, the magnetic hysteresis loop showed that the bimetallic Co-Cu nanowires we...

Using first-principles theory, we predict ferromagnetism in Cr-doped GaN nanowires irrespective of the sites that the Cr atoms occupy. This is in contrast to Mn-doped GaN nanowires in which the magnetic coupling between the Mn atoms is sensitive to the Mn--Mn and Mn--N distances, although the ground state of Mn-doped GaN nanowires is ferromagnetic. Each Cr atom carries a magnetic moment of abou...

Ni-doped TaSi2 nanowires were synthesized by annealing NiSi2 film as the mediated layer in a Ta reductive ambient at 950 ◦C for 16 h. The hysteresis loop has a hard magnetization axis and high remanence with a coercive force of 120 Oe when the applied magnetic field is perpendicular to the substrate (parallel to the nanowires) and the hysteresis loop has an easy magnetization axis and low reman...

A single-bath electrodeposition method was developed to integrate multilayer Ag/Co nanowires with a commercial anodic alumina oxide (AAO) template with a pore diameter of 100-200 nm. An electrolyte system containing silver nitride and cobalt sulfide was studied using cyclic voltammetry, and the electrodeposition rate was varied to optimize the electrodeposition conditions. A constant stepwise p...

The array of numerous metallic nanowires with straight shape has much attention due to their shape anisotropy and extremely large surface area. This unique structure can be applied to develop the novel functional nano-materials such as electronic, magnetic and optical nano-scale devices. Metallic nanowires can be fabricated by manipulating metallic atoms one by one using a scanning tunneling mi...

Anodic aluminum oxide (AAO) fabricated by two step anodization technique, is used as a template to synthesize FeCo nanowire arrays by AC electrodeposition technique. Response surface methodology (RSM) is applied to design the experiments, fit an empirical model and optimize the conditions to achieve the best magnetic properties. The magnetic properties, pore dimensions, composition and structur...
