Аннотация: This work contains the results of complex experimental research of the compounds EuLnCuS3 (Ln = La-Lu) enhanced by the DFT calculations. It is aimed at the data replenishment with particular attention to the revelation of regularities in the property changes, in order to extend the potential applicability of the materials of the selected chemical class. The ab initio calculations of the fundamental vibrational modes of the crystal structures were in good agreement with experimental results. The wavenumbers and types of the modes were determined, and the degree of the ion participation in the modes was also estimated. The elastic properties of the compounds were calculated. The compounds were found out to be IR-transparent in the range of 4000–400 cm–1. The estimated microhardness of the compounds is in the range of 2.68–3.60 GPa. According to the DSC data, the reversible polymorphous transitions were manifested in the compounds EuLnCuS3 (Ln = Sm, Gd-Lu): for EuSmCuS3 Tα↔β = 1437 K, ΔНα↔β = 7.0 kJ·mol-1, Tβ↔γ = 1453 K, ΔНβ↔γ = 2.6 kJ·mol-1; for EuTbCuS3 Tα↔β = 1478 K, ΔНα↔β = 1.6 kJ·mol-1, Tβ↔γ = 1516 K, ΔНβ↔γ = 0.9 kJ·mol-1, Tγ↔δ = 1548 K, ΔНγ↔δ = 1.6 kJ·mol-1; for EuTmCuS3 Tα↔β = 1543 K, Tβ↔γ = 1593 K, Tγ↔δ = 1620 K; for EuYbCuS3 Tα↔β = 1513 K, Tβ↔γ = 1564 K, Tγ↔δ = 1594 K; for EuLuCuS3 Tα↔β = 1549 K, Tβ↔γ = 1601 K, Tγ↔δ = 1628 K. In the EuLnCuS3 series, the transition into either ferro- or ferrimagnetic states occurred in the narrow temperature range from 2 to 5 K. The tetrad effect in the changes of incongruent melting temperature and microhardness conditioned on rLn3+ as well as influencing of phenomenon of crystallochemical contraction were observed. For delimiting between space groups Cmcm and Pnma in the compounds ALnCuS3, the use of the tolerance factor t’ = IR(A)·IR(C) + a×IR(B)2 was verified.

Заглавие : Effect of crystal size on the crystalline structure and magnetic properties of cobalt films obtained via chemical deposition
Место публикации : Bull. Russ. Acad. Sci. Phys. - 2022. - Vol. 86, Is. 5. - P.614-617. - ISSN 10628738 (ISSN), DOI 10.3103/S1062873822050045
Примечания : Cited References: 18
Аннотация: A study is performed of the relationship between the sizes of cobalt crystallites and the coercive and anisotropic properties of Co–P films obtained via chemical deposition. The emergence of induced anisotropy in films obtained at low pH (7.2–8.7) is due to size effects that transform the cobalt’s crystal lattice from face-centered cubic to hexagonal close-packed as the film grows in a magnetic field.

Аннотация: Anomalous mechanical materials, with counterintuitive stress-strain responding behaviors, have emerged as novel type of functional materials with highly enhanced performances. Here we demonstrate that the materials with coexisting negative, zero and positive linear compressibilities can squeeze three-dimensional volume compressibility into one dimension, and provide a general and effective way to precisely stabilize the transmission processes under high pressure. We propose a “corrugated-graphite-like” structural model and discover lithium metaborate (LiBO2) to be the first material with such a mechanical behavior. The capability to keep the flux density stability under pressure in LiBO2 is at least two orders higher than that in conventional materials. Our study opens a way to the design and search of ultrastable transmission materials under extreme conditions.

Заглавие : Degenerate bound states in the continuum in square and triangular open acoustic resonators
Место публикации : Phys. Rev. B. - 2022. - Vol. 106, Is. 8. - Ст.085404. - ISSN 24699950 (ISSN), DOI 10.1103/PhysRevB.106.085404
Примечания : Cited References: 43
Аннотация: We consider square and equilateral triangular open acoustic resonators with the C4v and C3v symmetries, respectively. There is a unique property of square and triangular resonators of accidental number fourfold degeneracy of eigenstates that gives rise to twofold-degenerate Friedrich-Wintgen (FW) bound states in the continuum (BICs). Compared to usual FW BICs, the degenerate FW BICs maintain high Q factor in wide range of the size of resonators. That removes the fabrication difficulties of the proper choice of resonator. The presence of degenerate BICs in triangular resonators is extremely sensitive to switch output flows by small perturbations with 100% efficiency.

Аннотация: Perovskite-based nanocomposites have garnered significant interests due to their potential in interfacial engineering, optical modification, and stability enhancement. However, current understanding of the construction models between perovskites and guest materials is limited, and the design concept of perovskite-based nanocomposites remains unclear. Herein, we thoroughly investigate the effects of amino bridge linkage in attapulgite@perovskite nanocomposites on the crystallization kinetics, optical properties, and stabilities of perovskites by monitoring the difference in structural, compositional, and morphological characteristics. The attapulgite@perovskite nanocomposite with amino bridge linkage exhibited a smaller average size distribution of 23.8 ± 5.8 nm, along with enhanced thermal stability (81% relative PL intensity after a heating-cooling cycle) and photo-stability (84% relative PL intensity after 30 h ultraviolet light irradiation). These improvements can be attributed to the adequate passivation of amino bridge linkages. Our work aims to provide a deeper understanding of perovskite-based nanocomposite construction and inspire new approaches for modifying their optical properties and enhancing their stability.

Аннотация: Phase transitions can change the crystal structure and modify the physical properties of crystals. In this work, we investigate the phase transition behavior in BaGa4Se7, an important middle infrared (mid-IR) nonlinear optical (NLO) crystal, in the temperature range from room temperature to 1173 K. Interestingly, the BaGa4Se7 crystal undergoes a reversible ferroelastic phase transition at T = 528 K, resulting in the presence of a newly discovered phase (γ-phase) at the higher temperature. The experimental temperature dependence of optical birefringence, as well as the first-principles birefringence and NLO coefficients, reveals that the γ-phase exhibits larger birefringence and better NLO properties compared with those of the low-temperature phase (α-phase). This work demonstrates that phase-transition-induced structural modification can improve the mid-IR NLO properties, which would provide an effective avenue to obtain materials with good optoelectronic performance.

Аннотация: New binuclear MnPt µ-vinylidene complexes Cp(CO)2Mn(µ-C=CHPh)Pt(CN–Ad)(L) [L=PPh3 (1a), P(OPri)3 (2a)] bearing a terminal platinum-coordinated 1-adamantyl isocyanide ligand were prepared by the treatment of Cp(CO)2Mn(µ-C=CHPh)Pt(CO)(L) [L=PPh3 (1b), P(OPri)3 (2b)] with CN-Ad. At the same time the reaction between Cp(CO)2Mn(µ-C=CHPh)Pt(L)2 [L=PPh3 (1c), P(OPri)3 (2c)] and CN-Ad did not proceed. The new complexes were characterized by IR and 1H, 13C, 31P NMR spectroscopy. The molecular structure of Cp(CO)2Mn(µ-C=CHPh)Pt(CN–Ad)[P(OPri)3] (2a) was determined by an X-ray diffraction study. The redox properties of the new complexes and their reactions of chemical oxidation were studied. An influence of the platinum-coordinated 1-adamantyl isocyanide ligand on the properties of the synthesized µ-vinylidene compounds 1a and 2a was revealed.

Ключевые слова (''Своб.индексиров.''): babf--anisotropic thermal expansion--phonon stimulation--nlo optical--property--low temperature
Аннотация: Thermal expansion is a crucial factor for the performance of laser devices, since the induced thermal stress by laser irradiation would strongly affect the optical beam quality. For BaAlBO3F2 (BABF), a good non-linear optical (NLO) crystal, due to the highly anisotropic thermal expansion its practical applications are strongly affected by the “tearing” stress with the presence of local overheating area around the laser spot. Recently, the strategy to place the optical crystals in low-temperature environment to alleviate the influence of the thermal effect has been proposed. In order to understand the prospect of BABF for this application, in this work, we investigated its thermal expansion behavior below room temperature. The variable-temperature XRD showed that the ratio of thermal expansion coefficient between along c- and along a(b)- axis is high as 4.5:1 in BABF. The Raman spectrum combined with first-principles phonon analysis revealed that this high thermal expansion anisotropy mainly ascribe to progressive stimulation of the respective vibration phonon modes related with the thermal expansion along a(b)- and c-axis. The good NLO performance in BABF can be kept below room temperature. The work presented in this paper provides an in-depth sight into the thermal expansion behavior in BABF, which, we believe, would has significant implication to the manipulation in atomic scale on the thermal expansion of the materials adopted in strong-field optical facility.
