Аннотация:
A sequence of phases forming during the solid-phase reaction in Al/Pt bilayer thin films has been investigated by in situ electron diffraction. It is shown that the amorphous PtAl2 phase forms first during the solid-phase reaction initiated by heating. Upon further heating, PtAl2, Pt2Al3, PtAl, and Pt3Al crystalline phases sequentially form, which is qualitatively consistent with an effective formation heat model. The content of phases forming during the reaction has been quantitatively analyzed and the structural phase transformations have been examined.

borates, which are nonmagnetic representatives of the RMe3(BO3)4 single crystals family (where R=Y, La-Lu; M=Fe, Al, Cr, Ga, Sc) with unique properties of magnetoelectrics and multiferroics, has been studied. In the process of the numerical simulation of the acoustic waves characteristics, the values of linear electromechanical constants of YAl3(BO3)4 single crystals, previously measured by ultrasonic pulse echo and quasi-static methods, have been used.

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.

Аннотация:
We demonstrate the possibility of using transparent conducting oxides [
aluminum
-doped zinc oxide (AZO), gallium-doped zinc oxide (GZO), indium tin oxide (ITO)] to form Tamm plasmon polaritons in the near-infrared spectral range where the permittivity of oxides is near zero. The spectral properties of the structures are investigated in the framework of the temporal coupled-mode theory and confirmed by the transfer matrix method. It is found that in the critical coupling conditions, the maximal Q-factor of a Tamm plasmon polariton is achieved when a photonic crystal is conjugated with the AZO film, while at the conjugation with the ITO films, the broadest spectral line is obtained. The sensitivity of the wavelength and spectral width of the Tamm plasmon polariton to changes in the oxide film thickness, bulk concentration of a dopant, and angle of incidence is demonstrated.

Аннотация:
The quantum spin systems Cu2M′BO5 (M′=Al,Ga) with the ludwigite crystal structure consist of a structurally ordered Cu2+ sublattice in the form of three-leg ladders, interpenetrated by a structurally disordered sublattice with a statistically random site occupation by magnetic Cu2+ and nonmagnetic Ga3+ or Al3+ ions. A microscopic analysis based on density-functional-theory calculations for Cu2GaBO5 reveals a frustrated quasi-two-dimensional spin model featuring five inequivalent antiferromagnetic exchanges. A broad low-temperature 11B nuclear magnetic resonance points to a considerable spin disorder in the system. In zero magnetic field, antiferromagnetic order sets in below TN≈4.1 K and ∼2.4 K for the Ga and Al compounds, respectively. From neutron diffraction, we find that the magnetic propagation vector in Cu2GaBO5 is commensurate and lies on the Brillouin-zone boundary in the (H0L) plane, qm=(0.45,0,−0.7), corresponding to a complex noncollinear long-range ordered structure with a large magnetic unit cell. Muon spin relaxation is monotonic, consisting of a fast static component typical for complex noncollinear spin systems and a slow dynamic component originating from the relaxation on low-energy spin fluctuations. Gapless spin dynamics in the form of a diffuse quasielastic peak is also evidenced by inelastic neutron scattering. Most remarkably, application of a magnetic field above 1 T destroys the static long-range order, which is manifested in the gradual broadening of the magnetic Bragg peaks. We argue that such a crossover from a magnetically long-range ordered state to a spin-glass regime may result from orphan spins on the structurally disordered magnetic sublattice, which are polarized in magnetic field and thus act as a tuning knob for field-controlled magnetic disorder.

Аннотация:
A commercial ANSYS FE Code is employed for the simulation of the electromagnetic sheet-metal forming into a grooved die. An industrial pancake coil is considered as the forming tool. The deformation characteristics of the sheet (workpiece) as well as the electromagnetic parameters of the high-energy process are calculated numerically. An equivalent-circuit method is used to validate the electromagnetic model. The results from both analyses are in good agreement.

The parameters of the spin Hamiltonian of Cr3+ ions in the YАl3(ВО3)4 matrix are determined at different temperatures. The sign of the fine structure parameter D allows the conclusion that the chromium ions in YА13(ВО3)4 single crystals have an easy-plane anisotropy.

Single crystals of yttrium
aluminum
borate YAl3 (BO3)(4) doped with manganese ions are studied using electron paramagnetic resonance spectroscopy. It is shown that manganese ions introduced at low concentrations into the sample predominantly occupy yttrium ion sites in the crystal structure. The shape of the electron paramagnetic resonance spectrum unambiguously indicates that the valence of manganese ions in this case is equal to 2+. The parameters of the spin Hamiltonian of Mn2+, ions in the YAl3(BO3)(4) matrix are determined at room temperature. The magnitude and sign of the fine structure parameter D allow the conclusion that the YAl3(BO3)(4) single crystals doped with manganese ions have a strong crystal field at the yttrium ion sites and L easy-axis anisotropy.

The isobaric heat capacity Cp(T) of YbAl3(BO3)4 grown by spontaneous crystallization from solution (100 − n) wt % (Bi2Mo3O12 + 2.5% B2O3 + 0.75% Li2MoO4) + n wt % YbAl3(BO3)4 is studied experimentally in the region of 344–1016 K. It is established that there are no extrema on the Cp(T) dependence, and the obtained data can be described using the Berman-Brown polynomial. The temperature variations of enthalpy and entropy are calculated from the Cp(T) dependence.

Recently discovered magnetoelectricity in the rare-earth
aluminum
borates RAl3(BO3)4 has attracted attention due to the large values of magnetoinduced electric polarization. We have observed for the first time the magnetoelectric polarization in TbAl3(BO3)4 exhibiting anomalous temperature dependence: an electric polarization induced by in-plane magnetic field (P||a,H⊥c axis) which is small at low temperatures (4K), remarkably increases by almost an order of magnitude at high temperatures (150–300K). The observed nonmonotonic temperature behavior of the field-induced polarization, including a change of sign at ∼65–70K, is attributed to the competition of the ground and excited crystal-field states of Tb3+ ions. Quantum theory analysis, involving the combination of analytical and numerical methods, has enabled us to quantitatively describe the observed magnetic and magnetoelectric properties of TbAl3(BO3)4.
Недавно обнаруженное магнетоэлектричество в редкоземельных алюмоборатах RAl3 (BO3) 4 привлекло к себе внимание из-за больших значений магнитоиндуцированной электрической поляризации. Мы наблюдали в первый раз магнитоэлектрическую поляризацию в TbAl3 (BO3) 4, показывающую аномальную температурную зависимость: электрическая поляризация индуцируется в плоскости магнитного поля (Р | |, Н ⊥ оси с), и является небольшой при низких температурах (4K), Значительно увеличивается, почти на порядок величины, при высоких температурах (150-300 К). Наблюдаемая с изменением температуры немонотонность поляризации от поля, в том числе изменению знака на ~ 65-70 К, может быть отнесена к конкуренции между основном и возбужденном кристаллическим полем состояниями ионов ТЬ3 +. Теория квантового анализа, предполагающей сочетание аналитических и численных методов, позволила нам количественно описать наблюдаемые магнитные и магнитоэлектрические свойства TbAl3 (BO3) 4.

Аннотация:
The anodic behaviour of pre-oxidised and non-oxidised Cu−Al-based anodes (Cu−10Al and Cu−9.8Al−2Mn) in KF−AlF3−Al2O3 melts was studied through galvanostatic and potentiodynamic polarization techniques. The alloy compositions were oxidised for a short-term (8 h) at 700 °C, followed by galvanostatic polarization for 1 h at 800 °C with an applied current density of 0.4 A/cm2. The potentiodynamic curves were recorded with a sweep rate of 0.01 V/s. XRD analysis was conducted on frozen melt samples collected on the surface of the anode, and SEM observation was performed on the anode after the experiment to study the phases of the scales formed on the alloys. All the anode materials had a steady potential between 2.30 and 2.50 V(vs Al/AlF3). The corrosion rates of the anodes were calculated from the data acquired through potentiodynamic polarization. It was seen that pre-oxidised anodes possess a low corrosion rate compared to those without pre-oxidation treatment.

The temperature behavior of saturation magnetization and the temperature behavior of the integral signal intensity in electron magnetic resonance spectra is experimentally studied comprehensively using a low-dimensional Al2O3/Ge/Al2O3/Co (
aluminum
oxide–cobalt–
aluminum
oxide–germanium) tunnel junction with different deposition velocities of a ferromagnetic metal (Co) thin layer and non-magnetic layers (Al2O3/Ge/Al2O3). The cobalt ferromagnetic layer was deposited on
aluminum
oxide in two ways: in one cycle of creating the structure and with atmospheric injection before deposition of the cobalt layer. The thermomagnetic curves revealed the appearance of minima observed at low temperatures on both sides of the cobalt layer. Possible sources of precession perturbations at low temperatures can be explained by: the influence of the Al2O3 layer structure on the Al2O3/Co interface; residual gases in the working chamber atmosphere and finely dispersed cobalt pellets distributed over the cobalt film thickness. The work offers information of great significance in terms of practical application, for both fundamental physics and potential applications of ultrathin films.
