“…Многие металлические стекла (МС) на основе железа выделяются своими высокими магнитными и механическими характеристиками. Роль поверхности в зарождении деформационных дефектов, развитии деформации и разрушения МС, фазовых переходах под влиянием нагрузки и температуры является предметом многочисленных исследований [1][2][3][4][5][6][7][8][9][10][11][12]. Однако известные в литературе экспериментальные и теоретические данные о поведении поверхностных слоев в процессе деформации и разрушение этих материалов являются часто противоречивыми и носят дискуссионный характер.…”

“…В работах [10][11] рассматривались влияние внешнего напряжения и состояния исходной поверхности на рельеф поверхностей разрыва. В работе [12] исследовались стороны контактные и неконтактные относительно барабана, на который " выстреливается" расплав, которые имеют различные скорости охлаждения. Это приводит к различию в свободном объеме, который содержит микропоры.…”

The micro- and nanoreliefs of the loaded surfaces of a Fe_77Ni_1Si_9B_13 metal glass are probed via scanning tunneling and atomic force microscopies, scanning electron microscopy, and X-ray fluorescence. The fractal characteristics of surfaces are evaluated via the multifractal approach. As found, the variations in a singularity spectrum width, calculated from the tunneling and atomic force microscopies, may be useful for predicting the forthcoming fracture. An increase in the breaking strength of ribbons subjected to hydrostatic compression is due to decreasing microporosity of a near-surface layer, which corresponds to the surface smoothing.

“…This value of a is also close to a ¼ 0.82 AE 0.05 found in Ag/SiO 2 [10]. However, the roughness exponent a was reported to be higher in some systems, like Au/Si(111) (a ¼ 1.4 AE 0.1) [11] and Au/mica (a ¼ 1.2 AE 0.2) [12], and lower in some other systems, like Ag/Au/Cr/SiO 2 (a ¼ 0.59 AE 0.05) [13]. These differences might indicate different (conservative or nonconservative) dynamical growth mechanisms in these systems [9].…”

Gold nanostructures were formed when Au nanolayers were deposited on native‐oxide‐covered Si substrates and annealed. To analyze the annealing temperature dependent surface morphology, we calculated the height–height correlation function and the power spectrum density function from the atomic force microscopy image data. When the annealing temperature for 20 nm thick Au layer increased from 500 to 700 °C, the interface width w and the lateral correlation length ξ of the surface increased obviously from 4.8 to 44.0 nm and from 70.5 to 180.9 nm, respectively. On the other hand, the roughness exponent α was a relatively universal parameter (∼0.87). While the morphology of the surfaces was mainly self‐affine, suggesting that the random surface diffusion plays a dominant role in the kinetic roughening process of such an annealed system, the results of the morphological analysis also imply that the self‐affine surface begins to become mounded for higher annealing temperatures.

Fractal and multifractal are the most important processes and concepts in describing and examining surface morphology, and for this reason, these concepts are an important approach for analyzing the properties and surface geometry of thin films. In this article, multifractal analysis was performed on images, prepared using atomic force microscopy (AFM), of the surface morphology of nickel oxide thin films deposited by RF‐Magnetron sputtering at different thicknesses on the glass substrate. The effect of thickness on the surface properties of the layers was studied by applying multifractal and statistical methods on AFM images. The results obtained from the multifractal spectrum show that the surface of the nickel oxide thin films deposited at different thicknesses are multifractal. The multifractal analysis demonstrated that multifractality and complexity of the surface of nickel oxide thin films changes and decrease with thicknesses. We also used statistical parameters to better examine AFM images to study the effects of layers thickness on the deposited NiO thin films. The results indicated that the statistical parameters are a function of the layer's thickness of NiO thin films. Hence, the isotropic properties and functional parameters changed with changing surface thickness. Research Highlights Multifractal analysis was applied to the AFM images to study the surface morphology of NiO thin films. The multifractal nature of the surface of NiO thin films is observed. The layers have become more isotropic with increasing thickness. The results illustrated that deposition masses occurred more at the highest sites on the surface. Multifractality of the surface of the sample decreased with increasing layer thickness.
