stripline resonator -- quality factor -- bandpass filter -- atomic-layer deposition
Аннотация: It is shown that for an optimal substrate thickness ALD technology will be promising for IF bandpass filter designing. A two-conductor stripline ALD resonator with central frequency 200 MHz will have Q-factor 53 with total length 3.7 mm (0.0025λg) and the frequency separation of the first and the second oscillation modes up to 59. Two bandpass filters for VHF and UHF designed and fabricated for commercial application display good agreement between the simulation and the experiment. A 3-pole bandpass filter with central frequency 255 MHz and lateral size 15.8×3.2 mm2 has stopband width 13.5f0 , and a 6-pole bandpass filter with central frequency 1250 MHz and lateral size 4.4×5.1 mm2 has stopband width 9.4f0.

Co–P thin magnetic films -- chemical deposition -- nuclear magnetic resonance -- allotropic modifications of Co
Аннотация: The effect of the solution acidity on the crystal structure of cobalt during its chemical deposition is reported. It has been shown using the structural and magnetic examination and nuclear magnetic resonance study that the change in the working solution acidity leads to deposition of cobalt with different allotropic modifications in the nearest environment: the hcp type in the small (up to ~8.5) pH region and the fcc type in the large (over ~8.5) pH region. The formation of these cobalt modifications is attributed to the size effects caused by a decrease in the particle size with increasing pH.

Аннотация: The paper presents the results of the formation and study of the morphological and structural characteristics of the mesoporous ZnO / Al2O3 nanofibers film (ZANF). The deposition of a ZnO layer on Al2O3 nanofibers film (ANF) ~ 1 µm thick was carried out by the method of atomic layer deposition. The morphology of the mesoporous composite layer ZnO / Al2O3 (ZANF) has been studied by scanning and transmission electron microscopy. It is shown that in the process of atomic layer deposition, the ZnO layer grows according to the Stranski-Krastanov mechanism. A ZnO layer less than 5 nm thick gives an island structure in which Al2O3 nanofibers are uniformly coated with ZnO particles, an increase in the ZnO layer thickness to 15 nm demonstrates a continuous coating of Al2O3 nanofibers. The system has a core-shell structure. The resulting composite structures are promising for applications in photocatalysis and gas sensing.

МАХ phases -- chromium germanides -- epitaxial thin films -- Auger electron spectroscopy -- magnetron sputtering co-deposition
Аннотация: Auger electron spectroscopy was used to determine the phase composition of Cr2GeC MAX phase thin films. A distinctive feature of the formation of carbon-containing MAX phases is the shape of carbon Auger peaks, which is characteristic of metal carbides spectra. Features of the Auger spectra in the presence of secondary phases of chromium germanides are found. Their presence can manifest itself in an increase in the energy of the germanium peaks, which is caused by a chemical shift during the formation of the Cr–Ge bond. Moreover, we have detected the accumulation of electronic charge, which can be explained by the features of the surface morphology.

Аннотация: Distribution of the magnetic anisotropy in thin film prepared by thermal vacuum oblique deposition of permalloy with small off-normal angle of incident in the presence of an external magnetic field has been studied by ferromagnetic resonance technique. On local area of the sample, a mutual compensation of near orthogonal in-plane uniaxial magnetic anisotropies induced by oblique deposition and by applied magnetic field has been found. Moreover, in addition to the uniaxial (twofold) magnetic anisotropy, fourfold and sixfold magnetic anisotropies have been observed in the sample. To explain the obtained high-order anisotropies, we assumed that the sample has exchange coupled adjacent regions or phases with different parameters of magnetic anisotropy. The results of the micromagnetic analysis of a two-layer model of the sample confirm the hypothesis. © 2015 Elsevier B.V. All rights reserved.

oblique angle deposition -- simulation of film growth -- Monte Carlo method
Аннотация: Based on the Monte Carlo method, a model of growth of thin films prepared by oblique angle deposition of particles is constructed. The morphology of structures synthesized by simulation is analyzed. To study the character of distribution of microstructural elements (columns) in the film plane, the autocorrelation function of the microstructure and the fast Fourier transform are used. It is shown that with increasing angle of particle incidence, the film density monotonically decreases; in this case, anisotropy arises and monotonically increases in the cross sections of columns, and the anisotropy of distribution of columns in the substrate plane also increases.

bulk nanostructured materials -- dynamic compaction -- plasma spray deposition -- magnetic properties
Аннотация: The bulk nanostructured Co58Ni10Fe5B16Si11 alloys were prepared by dynamic compaction and plasma spray deposition techniques. The investigation of structure and magnetic properties of bulk samples was carried out by X-ray diffraction, electron microscopy and correlation magnetometry. The bulk samples produced by both methods can be characterized as a heterophase system. The highest value of permeability 20 · 103 for plasma spraying coating is achieved when volume fraction of nanocrystalline phase with Curie temperature Tc ∼ 640 K is increased to 30%. The magnetic characteristics, such as the saturation magnetization, the Bloch constant, the local magnetic anisotropy field, the ferromagnetic resonance linewidth, and the coercivity remain unchanged after both compaction techniques. It was shown that the plasma spraying method allows to obtain bulk magnetically soft materials with magnetic parameters that are not inferior to the characteristics of a thermally treated rapidly quenched ribbon with the same composition.

Аннотация: A novel apatite phosphor Ca6La4(SiO4)2(PO4)4O2:Eu2+ was prepared by conventional high-temperature solid-state reaction. Phase purity was examined by XRD and XPS analysis. The crystal structure information, such as space group, cell parameters and atomic coordinates, were refined by the Rietveld method, revealing that Eu2+ occupied the sites of Ca2+ ions. Moreover, low-temperature experiments, including low-temperature PL spectra and low-temperature decay curve, were used to prove the existence of two luminescence centers in Ca6La4(SiO4)2(PO4)4O2:Eu2+. With the increase in doping concentration of Eu2+, the emission wavelength shows a red shift from 498 nm to 510 nm, which is mainly caused by the increase in crystal-field splitting by Eu2+. The optimized concentration of Eu2+ was confirmed to be 0.01, the Rc was calculated to be 20.09 Å and the energy transfer between Eu2+ was demonstrated to be by exchange interaction. Moreover, good thermal stability has been proved by a temperature-dependence experiment; it shows that the phosphor can maintain 55% of emitting intensity at 150 °C compared to that at room temperature. Finally, the Ca6La4(SiO4)2(PO4)4O2:Eu2+ phosphor was fabricated with commercial red (CaAlSiN3:Eu2+) and blue (BAM:Eu2+) phosphor coating on a n-UV chip. This proves that this green phosphor has the potential to be used in a w-LED lamp.

Аннотация: Coercivity of amorphous Co-P single-layer and trilayer films fabricated by chemical deposition has been investigated. It has been established that the thickness dependences of the coercivity for isotropic and anisotropic films are different. Data on the coercivity variation with a nonmagnetic spacer thickness and a number of magnetic layers in the trilayer films are reported. The results obtained are analyzed with regard to the features of the induced anisotropy in amorphous ferromagnetic films and the magnetic coupling between magnetic layers in sandwich structures.© (2014) Trans Tech Publications, Switzerland.

multilayer magnetic films -- interlayer interaction -- dipole coupling field -- coercivity
Аннотация: The results of experimental and theoretical studies of the coercivity and the dipole coupling field of the hysteresis loop on the thickness of the nonmagnetic interlayer in magnetic films, which are obtained via chemical deposition, are presented. Using model calculations based on the Landau–Ginzburg equations, the exchange interactions between magnetic layers with the participation of atoms from the nonmagnetic interlayer are studied. The resulting expression for the dipole coupling field describes well the exponential changes in the dipole coupling field as a function of the interlayer thickness in structures with both soft magnetic layers and layers with significantly different values of the coercivity.

Аннотация: Bulk nanostructured Co–P/Cu and Al2O3/Co–P composites are fabricated via dynamic compaction. The initial core–shell particles are synthesized by means of chemical deposition. Structural and magnetic characteristics of the composites are investigated. It is shown that the use of composite particles allows homogeneous compacts with the structure and magnetic characteristics of initial powders to be obtained. © 2016, Allerton Press, Inc.

sandwich structure -- exchange bias -- coercivity -- magnetization reversal
Аннотация: Exchange bias and coercivity of the hysteresis loop of a low-coercive layer in magnetic three-layered structure prepared by chemical deposition are studied. It is established that the coercive force in the films obtained nonmonotonically changed with the low-coercive layer thickness. The specificity of magnetization reversal of exchange-biased layers is analyzed.

Аннотация: The reactions of aqueous gold complexes with H2Se and H2S are important for transportation and deposition of gold in nature and for synthesis of AuSe-based nanomaterials but are scantily understood. Here, we explored species formed at different proportions of HAuCl4, H2Se and H2S at room temperature using in situ UV-vis spectroscopy, dynamic light scattering (DLS), zeta-potential measurement and ex situ Transmission electron microscopy (TEM), electron diffraction, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and Raman spectroscopy. Metal gold colloids arose at the molar ratios H2Se(H2S)/HAuCl4 less than 2. At higher ratios, pre-nucleation “dense liquid” species having the hydrodynamic diameter of 20–40 nm, zeta potential −40 mV to −50 mV, and the indirect band gap less than 1 eV derived from the UV-vis spectra grow into submicrometer droplets over several hours, followed by fractional nucleation in the interior and coagulation of disordered gold chalcogenide. XPS found only one Au+ site (Au 4f7/2 at 85.4 eV) in deposited AuSe, surface layers of which partially decomposed yielding Au0 nanoparticles capped with elemental selenium. The liquid species became less dense, the gap approached 2 eV, and gold chalcogenide destabilized towards the decomposition with increasing H2S content. Therefore, the reactions proceed via the non-classical mechanism involving “dense droplets” of supersaturated solution and produce AuSe1−xSx/Au nanocomposites.

Аннотация: The comparison between the magnetic properties of materials with different curvature and spatial distribution of nanograins, such as particles (3D spatial distribution) and multilayer films (2D) was carried out. Functionally graded Co(P)/Ni(P) and Co(P)/CoNi(P) specimens have been fabricated by electroless deposition. The magnetic and structural properties are characterized by electron microscopy, X-ray diffraction, ferromagnetic resonance spectroscopy, and vibrating sample magnetometer. It was demonstrated that the interaction between the Ni(P) core and Co(P) shell of particles could form the functionally graded materials with tailored structure and coercive force. Furthermore, it was found that the magnetic parameters (the local anisotropy field, ferromagnetic resonance linewidth, and coercivity) are mainly determined by the artificially created interface boundaries for all grains’ spatial distribution. The magnetic anisotropy field and coercivity of Co(P)/Ni(P) flat films were characterized by lower values than those for spherical shell of particles with the same composition, produced by the same method.
