“…It is caused by their unique combination of tribological, electrical and electrical properties [1] , which allows them to serve as an alternative to chromium coatings [2] . Also, these films with a columnar structure and a perpendicular magnetic anisotropy have a wide range of magnetic characteristics can be used for information recording devices with a high density [3] . Adding a third element to the binary alloy of tungsten in some cases it may improve the properties of the corrosive properties of such an alloy Co-Ni-W has better corrosion resistance than similar alloys electrodeposited amorphous Co-W [4] .…”

In this paper we investigated the structure of amorphous and nanocrystalline alloys of CoNiW obtained by electrolytic deposition. Studies were performed by transmission electron microscopy in HAADF mode and atomic force microscopy. In the course of the work was to obtain new data on the structure of materials. It has been found that tungsten is more homogeneous distributed in the alloy than nickel or cobalt. This is due to higher mobility of the atoms of nickel and cobalt in the electrolyte.

“…Thin magnetic films based on CoNiW alloys are promising as materials for perpendicular or near-perpendicular magnetic recording because of their columnar structure with perpendicular magnetic anisotropy [5-7]. Researchers are interested in these films because of their wide range of magnetic properties that are dependent on deposition conditions and chemical composition [4-6,8-10]. It is well known that the alloy structure of CoW-CoNiW-NiW may be nanocrystalline or amorphous depending on the composition and preparation conditions [7-14].…”

The structure of electrolytically deposited nanocrystalline alloys of the CoW-CoNiW-NiW systems under low-temperature heating was investigated by means of high-resolution transmission electron microscopy (HRTEM), high-angle annular dark-field scanning transmission electron microscopy (HAADF STEM), and analytical methods such as energy dispersive x-ray spectroscopy (EDS) and electron energy loss spectroscopy (EELS). Structural relaxation and crystallization were investigated at temperatures of 200°C to 300°C. The structural and compositional inhomogeneities were found in the CoW-CoNiW-NiW alloys, while the local changes in composition were found to reach 18 at.%. Nanocrystals in the alloys grew most intensely in the presence of a free surface, and we found their nuclei density to range from 2 × 1023 /m3 to 3 × 1023 /m3. It was determined that the local diffusion coefficient ranged from 0.9 to 1.7 10−18 m2/s, which could be explained by the prevalence of surface diffusion. The data gathered in these investigations can be used to predict the thermal stability of CoW-CoNiW-NiW alloys.
