Specific features of formation and growth mechanism of multilayered quasi-one-dimensional (Co-Ni-Fe)/Cu systems in pores of anodic alumina matrices

Abstract

A method for fabricating multilayered quasi one dimensional ferromagnet-diamagnet systems is described by the example of Co-Ni-Fe/Cu nanowires. The fabrication is implemented in a unified techno logical cycle from a combined electrolyte by pulsed potentiostatic electrodeposition. Regimes of the forma tion of layers of different systems, from pure ferromagnetic metals to alloys on their basis, are described. Mechanisms of nanowire growth are proposed. The distribution of chemical elements in the layers is investi gated as a function of the electrolyte composition and the fabrication conditions. The nanowire microstruc ture is investigated by high resolution scanning electron microscopy.

Effectiveness of the magnetostatic shielding by the cylindrical shells

“…The magnetic shields are formed by the electrodeposition method of the soft magnetic Fe 20 Ni 80 alloys [8]. The copper billets of cylindrical shape with an external diameter of 22 mm, an inner diameter of 20 mm and length of 40 mm were used as the substrates.…”

Post-processing of SiO2/Si ion-track template images for pores parameters analysis

“…This determines relevance of searching of methods for controlled synthesis of nanoobjects with predetermined characteristics. Among the wide variety of techniques template synthesis can be distinguished due to its simplicity, low price and high quality [7][8][9][10][11][12][13][14]. The method is based on using of porous matrices (which are templates based on polymer, silicon or oxide materials) as a form-building basis for realization of nanostructures [15][16][17][18][19][20][21][22].…”

Influence of deposition potential on structure of Zn-based nanotubes

“…For Zn-and ZnO-based nanostructures formation are mainly used chemical vapor deposition, arc discharge method, laser evaporation and template synthesis. The most attractive is the template synthesis method due to scalability, sufficient degree of control and low cost [11][12][13][14][15]. The template synthesis allows obtaining nanostructures with predetermined shape and dimensions.…”
