AB  - In this work we investigated the influence of different deposition angles on the structural and magnetic properties of nickel thin films obtained by Glancing Angle Deposition. The films were deposited onto glass substrates at the angles of 65° and 85°. The structure of the films was studied by scanning electron microscopy, atomic force microscopy and X-ray diffraction, while the magnetic properties were analyzed using magneto-optical Kerr effect microscopy (MOKE). It was found that the variation in the deposition angle has a great influence on the porosity, crystallinity and surface roughness of the Ni films. The obtained changes in microstructure were correlated with the variation in the magnetic properties. MOKE measurements revealed that the thinner films, deposited at the angle of 85°, have a 2.5 times higher coercivity in comparison with the films deposited at the lower angle, which can be ascribed to their higher porosity. © 2019 Elsevier Ltd

AB  - In this work, Glancing Angle Deposition technique was used for obtaining nanostructured nickel thin film with vertical posts on glass substrate which was positioned 75 degrees with respect to the substrate normal and rotated with a suitable constant speed. The obtained nickel thin film was characterized by Scanning Electron Microscopy, Atomic Force Microscopy and X-ray Photoelectron Spectroscopy. It was found that the deposited thin film consists of 94.0 at.% of nickel. Magnetic properties of the deposited thin film were determined by Magneto-Optical Kerr Effect Microscopy. According to the obtained coercivity values, it can be concluded that the nickel thin film shows uniaxial magnetic anisotropy.

AB  - Zig-zag structure of the nickel thin film has been obtained using Glancing Angle Deposition (GLAD) technique. Glass substrate was positioned 75 degrees with respect to the substrate normal. The obtained nickel thin film was characterized by X-ray Photoelectron Spectroscopy, Scanning Electron Microscopy and Atomic Force Microscopy. Surface energy of the deposited thin film was determined by measuring the contact angle using the static sessile drop method.

AB  - In this work, nickel (Ni) thin films were deposited by electron beam evaporation of Ni using Glancing Angle Deposition technique onto the glass substrate with the thickness varied from 25 nm to 150 nm. Characterization of obtained Ni films was performed by scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and by Magneto-Optical Kerr effect measurements (MOKE). The effect of thickness on structural, chemical and magnetic properties of nickel films has been studied. Observed changes in microstructure were correlated with the variation in magnetic parameters obtained by MOKE measurements. It was found that for thinner Ni films, the enhancement of coercivity is due to the surface roughness of Ni films, while for thicker films the observed asymmetry of coercivity is due to the mechanism of column size growth.

AB  - High density polyethylene (HDPE) has been modified by Ag+ and Au+ ion implantation with the energy of 60 and 200 keV, respectively. The doses of implanted silver and gold ions were as follows: 1 x 10(15), 5 x 10(15) and 1 x 10(16) ions/cm(2). The surface topography was observed using atomic force microscopy (AFM), while the surface composition changes were detected using phase imaging AFM. Phase analysis of AFM images shows that both physical and chemical changes occur on the surface of HDPE and that these changes depend on the nature of implanted ions and on the implantation dose. Silver ion implantation causes a higher degree of chemical changes, while the implantation of gold ions causes a higher degree of physical changes. Breakpoints were observed for the implantation doses of 0.6 x 10(15) and 4.4 x 10(15) ions/cm(2) for silver and gold ions, respectively. Physical changes are confirmed by the analysis of mean square roughness and power spectral density slopes as functions of the implantation dose. The position and half-width of peaks in histograms of phase AFM images confirmed the changes in surface composition.
