A series of Co1 xCux (x 1⁄4 0:05{0:70) composite nanowire arrays have been electrodeposited in alumina templates. An apparent pH value rule for nanowire phase and composition has been found. Based on it, composite nanowires can be obtained and the composition becomes more controllable. In the composite nanowires, the cubic and hexagonal structures coexisted. The specific magnetic properties, co...

UNLABELLED Si quantum dots (Si QDs)/SiC multilayers were fabricated by annealing hydrogenated amorphous Si/SiC multilayers prepared in a plasma-enhanced chemical vapor deposition system. The thickness of amorphous Si layer was designed to be 4 nm, and the thickness of amorphous SiC layer was kept at 2 nm. Transmission electron microscopy observation revealed the formation of Si QDs after 900°C ...

The use of the power and energy functional in the analysis of the electric circuits makes it possible to appreciate the energetic equilibrium state attained in the circuit at a certain moment. This paper is concerned with a demonstration of the principle of minimum dissipated active power for the steady state circuits under nonsinusoidal conditions. It is shown that the equilibrium state is one...

The structural and magnetic properties of Cu//Co and Au//Co multilayers are studied by X-ray absorption spectroscopy. The results of EXAFS measurements show that thin cobalt layers in Cu /Co and Au /Co multilayers have a different structure imposed by the mismatch with Cu (2%) and Au (14%). The most interesting results for Cu/Co multilayers are provided by magnetic circular X-ray dichroism (MCX...

Magnetic materials with perpendicular magnetic anisotropy (PMA) have wide-ranging applications in magnetic recording and sensing devices. Multilayers comprised of ferromagnetic and non-magnetic metals (FM-NM) are interesting materials, as their magnetic anisotropy depends strongly on composition and growth parameters. In this context, (Co/Pd) multilayers have gained huge interest recently due t...
