	abstract = {In this work, thin films of aluminum doped ZnO (AZO) were deposited on ultrasonically cleaned\&nbsp;glass substrates\&nbsp;by\&nbsp;sol-gel process\&nbsp;using dip and spin\&nbsp;coating techniques. For this purpose, Zinc acetate dihydrate, aluminum nitrate nonahydrate, ethanol and mono\&nbsp;ethanolamine\&nbsp;were employed as precursor,\&nbsp;dopant, solvent and stabilizer, respectively.\&nbsp;X-ray diffraction, UV{\textendash}vis,\&nbsp;photoluminescence, 4-point probe and Van der pauw techniques were investigated for the characterization of the prepared AZO thin films.\&nbsp;X-ray-analysis\&nbsp;revealed that all the prepared films have hexagonal\&nbsp;wurtzite\&nbsp;structure with a relative preferential orientation along the c-axis and the\&nbsp;lattice parameters\&nbsp;are close to the standard values reported in literature.\&nbsp;UV{\textendash}vis spectroscopy\&nbsp;showed that the average value of the films{\textquoteright}\&nbsp;transmittance\&nbsp;in the visible region is found to be around 85\% and the gap ranges in the interval [3.15 eV{\textendash}3.30 eV]. The photoluminescence spectrum only showed the UV peak while the broad band of the visible region was completely vanished. The electrical measurements indicate that sol-gel methods provide relatively high\&nbsp;resistivities\&nbsp;compared to those obtained with physical\&nbsp;vapor deposition\&nbsp;(PVD) techniques.},

	The article describes a study on the influence of RF magnetron cathode sputter thickness, (09) Ni/NiO thin multilayer (each multilayer varies from 35{\r A} to 3000{\r A}). Measurements exploited by different MEB and XRD measurement techniques were obtained to give structural results and the average variation of the multilayer strength and the hysteresis cycles follow the two directions parallel and perpendicular to the substrate by VSM at room temperature. magnetic results.

	abstract = {: In the present work, thin films of Cr/NiO/Ni are deposited on glass substrates using RF magnetron sputtering technique. The uniformity and homogeneity of the prepared films were controlled by varying the power of the source, the targetsubstrate distance and the pressure of the plasma gas which is argon. In order to test the Preisach Model, we carried out measurements according to two directions: parallel and perpendicular to the substrate plane using a Vibrating Sample Magnetometer at room temperature. Good agreement has been obtained by comparing the experimental hysteresis loops to the ones determined using Preisach model. We conclude that this model is powerful in predicting the magnetic properties of multilayer systems.},

	abstract = {Zn(1{\textendash}x)MgxO thin films with various concentrations of magnesium were deposited using the spray pyrolysis method. The transmittance spectra recorded for all films exhibit maxima exceeding 90\%. The band gap energy of the films with wurtzite structure increases from 3.22 up to 3.60 eV by incorporating Mg into ZnO. However, when the atomic ratio of Mg exceeded 0.4, a second crystalline phase (assigned to cubic MgO) became discernable in XRD patterns, a compressive strain was observed in the wurtzite lattice, and crystallite sizes decreased significantly. In accordance with these observations, finer grains with a pronounced columnar growth were observed in 3D AFM representations and the surface roughness decreases significantly. Finally, selective etching in water yields to porous films with a great surface-to-volume ratio, a lower refractive index and a better light transmission. These porous films with tunable band gap seem to be excellent candidates to various interesting applications.},

The structure properties were analyzed using x-ray diffraction (XRD) and their magnetic hysteresis loops were obtained by Vibrating Sample Magnetometer (VSM) at room temperature. In this situation, the magnetic field is either parallel or perpendicular to the substrate plane. The main contribution of this work is to characterize the thin layers and present a mathematical model that can get best fit of the characteristics B(H). By using Preisach model, good agreement was obtained between theoretical and experimental results in both cases.},
