Chemical pressure as an effective tool for tuning the structural disordering and barocaloric efficiency of complex fluorides (NH4)3MF7 (M: Sn, Ti, Ge, Si) / I. N. Flerov, M. V. Gorev, E. V. Bogdanov, N. M. Laptash // J. Phys. D: Appl.

fluorides -- phase transformation -- phase diagram -- entropy -- pressure -- barocaloric effect
Аннотация: Double fluoride salts (NH4)3M4+F7 (M4+: Sn, Ti, Ge, Si) demonstrate a high efficiency of using chemical pressure as a tool for control and tuning structural ordering/disordering, sensitivity to hydrostatic pressure, successions of the phase transitions, etc and, as a result, for purposeful variation within a wide range of parameters of barocaloric effect (BCE). The conventional and inverse BCEs near the triple points were found on the T − p phase diagrams, combination of which can be used to construct original cooling cycle in narrow temperature and pressure ranges. Reconstructive transformation between two cubic phases, Pm3-m ↔ Pa3-, realized in (NH4)3SnF7 at atmospheric pressure and in (NH4)3TiF7 at p ˃ 0.4 GPa are characterized by rather low thermal hysteresis, δT0 = 1 K, and a great entropy change, ΔSBCE = 110–152 J (kg · K)−1, depending on the size of the central atom. At above 300–350 K, a contribution to BCE associated with the regular thermal expansion of the crystal lattice becomes comparable to entropy and temperature changes under pressure in the region of the phase transitions. An analysis of the absolute, relative and integral barocaloric characteristics of (NH4)3M4+F7 compounds showed their high competitiveness with respect to other barocaloric materials considered as promising solid-state refrigerants.

A hybrid quantum–classical theory for predicting terahertz charge-transfer plasmons in metal nanoparticles on graphene / A. S. Fedorov, E. V. Eremkin, P. O. Krasnov [et al.] // J. Chem. Phys. - 2024. - Vol. 160, Is. 4. - Ст. 044117, DOI 10.1063/5.0178247. - Cited References: 61. - This study was funded by the Ministry of Science and High Education of Russian Federation, Project No. FSRZ-2023-0006. The calculations of CTPs in specific NP–graphene complexes were performed within the RSF Grant No. 23-12-20007 and the Krasnoyarsk Territorial Foundation for Support of Scientific and R & D Activities, Agreement No. 256. H. Ågren was supported by the Swedish Science Research Council on Contract No. 2022-03405 . - ISSN 0021-9606. - ISSN 1089-7690
Аннотация: Metal nanoparticle (NP) complexes lying on a single-layer graphene surface are studied with a developed original hybrid quantum–classical theory using the Finite Element Method (FEM) that is computationally cheap. Our theory is based on the motivated assumption that the carrier charge density in the doped graphene does not vary significantly during the plasmon oscillations. Charge transfer plasmon (CTP) frequencies, eigenvectors, quality factors, energy loss in the NPs and in graphene, and the absorption power are aspects that are theoretically studied and numerically calculated. It is shown the CTP frequencies reside in the terahertz range and can be represented as a product of two factors: the Fermi level of graphene and the geometry of the NP complex. The energy losses in the NPs are predicted to be inversely dependent on the radius R of the nanoparticle, while the loss in graphene is proportional to R and the interparticle distance. The CTP quality factors are predicted to be in the range ~ 10 – 100. The absorption power under CTP excitation is proportional to the scalar product of the CTP dipole moment and the external electromagnetic field. The developed theory makes it possible to simulate different properties of CTPs 3–4 orders of magnitude faster compared to the original FEM or the finite-difference time domain method, providing possibilities for predicting the plasmonic properties of very large systems for different applications.

composite material -- fiberglass -- nuclear magnetic resonance -- magnetic resonance imaging -- water absorption
Аннотация: The results of a study of water absorption processes by samples of polymer composite materials (PCMs) based on fiberglass, subjected to low-speed impact with controlled impact energy and alternating temperature cycling are presented. Using magnetic resonance imaging (MRI), the distribution of absorbed water in the fiberglass structure is visualized and the dynamics of its accumulation in various areas of the sample are studied. It is found that mechanical impact leads to a nonuniform distribution of the absorbed water in the samples and a significant accumulation of free water in the areas of destruction and adjacent layers in the event of a violation of the integrity of the outer layer of the material. It is shown that cyclic alternating temperature effects do not lead to a noticeable change in the water absorption processes and are comparable in effect to mechanical nondestructive impacts. The results obtained using MRI are in close agreement with the data of traditional weight measurements, which shows the effectiveness of the method in diagnosing defects and mechanical damage to PCMs exposed to the humid environment.

композиционный материал -- стеклопластик -- ядерный магнитный резонанс -- магнитно-резонансная томография -- водопоглощение
Аннотация: В работе представлены результаты исследования процессов водопоглощения образцами полимерных композиционных материалов на основе стеклопластика, подвергнутых низкоскоростному ударному воздействию с регулируемой энергией удара и знакопеременному температурному циклированию. С помощью метода магнитно-резонансной томографии (МРТ) визуализировано распределение поглощенной воды в структуре стеклопластика и изучена динамика ее накопления в различных областях образца. Обнаружено, что ударное механическое воздействие приводит к неоднородному распределению абсорбированной воды в образцах, а также к существенному аккумулированию свободной воды в областях разрушений и прилегающих к ним слоях в случае нарушения целостности внешнего слоя материала. Показано, что циклическое знакопеременное температурное воздействие не приводит к заметному изменению процессов водопоглощения и сопоставимо по своему эффекту с механическим неразрушающим воздействием. Полученные с помощью МРТ результаты хорошо согласуются с данными традиционных весовых измерений, что показывает эффективность метода в диагностике дефектов и механических повреждений полимерных композиционных материалов, подверженных воздействию водной среды.

Magnetic interparticle interactions and superparamagnetic blocking of powder systems of biogenic ferrihydrite nanoparticles / A. A. Krasikov, Yu. V. Knyazev, D. A. Balaev [et al.] // J. Exp. Theor. Phys. - 2023. - Vol. 137, Is. 6. - P. 903-913, DOI 10.1134/S1063776123120075. - Cited References: 58. - This study was supported by the Russian Science Foundation, project no. 22-72-00134 . - ISSN 1063-7761. - ISSN 1090-6509
Аннотация: The magnetic-field dependence of the superparamagnetic-blocking temperature TB of systems of antiferromagnetically ordered ferrihydrite nanoparticles has been investigated and analyzed. We studied two powder systems of nanoparticles: particles of “biogenic” ferrihydrite (with an average size of 2.7 nm), released as a result of vital functions of bacteria and coated with a thin organic shell, and particles of biogenic ferrihydrite subjected to low-temperature annealing, which cause an increase in the average particle size (to 3.8 nm) and burning out of the organic shell. The character of the temperature dependences of magnetization, measured after cooling in a weak field, as well as the shape of the obtained dependences TB(H), demonstrate peculiar features, indicating the influence of magnetic interparticle interactions. A detailed analysis of the dependences TB(H) within the random magnetic anisotropy model made it possible to estimate quantitatively the intensity of magnetic particle–particle interactions and determine the magnetic anisotropy constants of individual ferrihydrite particles.

Separating the contributions of the magnetic subsystems in antiferromagnetic ferrihydrite nanoparticles by analyzing the magnetization in fields of up to 250 kOe / A. A. Krasikov, D. A. Balaev, A. D. Balaev [et al.] // J. Magn. Magn. Mater. - 2024. - Vol. 592. - Ст. 171781, DOI 10.1016/j.jmmm.2024.171781. - Cited References: 84. - This study was supported by his work was supported by the Russian Science Foundation, project no. 22–72-00134. - Authors thank to D.A. Velikanov, S.V. Komogortsev for fruitful discussions . - ISSN 0304-8853. - ISSN 1873-4766
Аннотация: Contributions of different magnetic subsystems formed in the systems of synthetic ferrihydrite nanoparticles (characterized previously) with an average size of ˂d˃ ≈ 2.7 nm coated with polysaccharide arabinogalactan in different degrees have been separated by measuring the dependences of their magnetization M on magnetic field H of up to 250 kOe on vibrating sample and pulsed magnetometers. The use of a wide measuring magnetic field range has been dictated by the ambiguity in identifying a linear M(H) portion for such antiferromagnetic nanoparticle systems within the conventional field range of 60–90 kOe. The thorough analysis of the magnetization curves in the temperature range of 100–250 K has allowed the verification of the contributions of (i) uncompensated magnetic moments µun in the superparamagnetic subsystem, (ii) the subsystem of surface spins with the paramagnetic behavior, and (iii) the antiferromagnetic susceptibility of the antiferromagnetically ordered ferrihydrite particle core. As a result, a model of the magnetic state of ferrihydrite nanoparticles has been proposed and the numbers of spins corresponding to magnetic subsystems (i)–(iii) have been estimated. An average magnetic moment μun of ∼ 145 μB (μB is the Bohr magneton) per particle corresponds approximately to 30 decompensated spins of iron atoms in a particle (about 3 % of all iron atoms), which, according to the Néel’s hypothesis μun ∼ ˂d˃3/2, are localized both on the surface and in the bulk of an antiferromagnetically ordered particle. The fraction of free (paramagnetic) spins is minimal in the sample without arabinogalactan coating of the nanoparticle surface (7 %) and is attained 20 % of all iron atoms in the sample with the highest degree of spatial separation of particles. According to this estimation, paramagnetic spins are located mainly on the edges and protruding areas of particles. Most magnetic moments of iron atoms are ordered antiferromagnetically and the corresponding magnetic susceptibility of this subsystem behaves as in an antiferromagnet with the randomly distributed crystallographic axes, i.e., increases with temperature.

Magnetic anisotropy and ferromagnetic resonance in inhomogeneous demagnetizing fields near edges of thin magnetic films / P. N. Solovev, B. A. Belyaev, N. M. Boev [et al.] // J. Phys. Condens.

Кл.слова (ненормированные):
edge domain -- demagnetizing fields -- demagnetizing fields -- film edges -- magnetic anisotropy -- magnetization dynamics
Аннотация: Using local ferromagnetic resonance spectroscopy, we have studied the magnetic properties near edges of thin tangentially magnetized permalloy films, in which a well-defined uniaxial magnetic anisotropy was induced perpendicular to one of the edges. In the experiment, two samples with thicknesses of 90 and 300 nm and with slightly different compositions were examined. To explain the magnetization dynamics near edges, we propose a simple yet effective model of a film in the form of a rectangular prism, which yields the modified Kittel formula for the resonance frequency. In this formula, the locally averaged distance-dependent demagnetizing field that emerges near the edges is included as an additional uniaxial anisotropy term. The measurements reveal that at a certain distance from the edge, the resulting (apparent) anisotropy, determined from the angular dependencies of the resonance field, almost vanishes. Moreover, its easy axis reorients to become parallel to the edge. The model predictions agree well with these results, proving that the main resonance mode behavior near the film edges can be accurately described by introducing additional effective uniaxial anisotropy, provided the measuring area is relatively large. However, for the thick (300 nm) sample, additional precession modes are also observed. These modes distort the angular dependence of the main mode, thus demonstrating the limitations of the model.

Аннотация: The threshold structural transformation of the DUT-4 metal–organic framework (MOF) from an ordered to distorted phase during exposure to ambient conditions has been revealed. The in situ X-ray diffraction analysis, in situ Raman and FTIR spectroscopy, scanning electron microscopy and synchronous thermal analysis have been used for investigation. The reversible effect of exposure time and humidity on such a phase transition has been confirmed. We also demonstrated that the observed phase transition correlated well with changes in the optical and electronic properties of DUT-4, paving the way to a new family of MOF-based phase change materials for optoelectronic applications.

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.
