Magnetic nanorods or nanowires exhibit degrees of freedom associated with their inherent shape anisotropy and the ability to incorporate different components along their length. The introduction of multiple segments along the length of a nanowire can lead to further degrees of freedom associated with the shape of each segment and the coupling between layers. In this paper, we present an overview of the magnetic properties of single-component and multiple-segment magnetic nanowires, and we provide examples of the influence of particle diameter, aspect ratio, and composition on many of their magnetic properties: the orientation of their magnetic easy axis, their Curie temperature, coercivity, saturation field, saturation magnetization, and remanent magnetization.

Methods for Electrodepositing Composition-Modulated Alloys

Fretting wear of metallic multilayer films

Characterisation of Co-Ni(Cu)/Cu multilayers deposited from a citrate electrolyte in a flow channel cell

An electrodeposition technique for making multilayered thin films, based on controlled deposition from two different solutions, is described. Ni/NiPx and NiPx/NiPy multilayered thin films with repeat lengths as low as 20 A have been prepared. They show up to three low‐angle x‐ray peaks corresponding to the electron density modulation.

New dual‐bath technique for electrodeposition of short repeat length multilayers

The mechanical properties of electroplated alpha and beta brasses and of deposits consisting of alternate layers of the two phases were determined. The alternate-layer deposits were stronger than the single-phase ones only if the latter were coarse grained. Some alternate-layer deposits of ordered and disordered beta brass exhibited high ductilities, apparently due to a strain-induced martensitic reaction which inhibited necking. The friction coefficients of alternate-layer deposits being lower than those of the single-phase ones indicated weak bonding between the alpha and beta layers.
