Аннотация:
Fe3O4@C, Fe3O4@C@C, and Fe3O4@SiO2 core–shell nanoparticles are synthesized via thermal decomposition and coprecipitation. Samples are characterized via X-ray spectroscopy, transmission electron microscopy, and magnetometry. It is shown that the magnetic core of all nanoparticles is nanocrystalline and has crystal parameters corresponding to only one phase of Fe3O4, covered with a uniform shell of amorphous carbon or silicon oxide around 8 nm thick. Special attention is given to adsorption properties of the nanoparticles with respect to four dyes: Methylene blue, Congo Red, Eosin Y, and Rhodamine C. The high selectivity of Fe3O4@C nanoparticles to various dyes is revealed.

Catalytic activity of nanoparticles
Аннотация:
The morphology and magnetic properties as well as adsorption capacity and catalytic activity of Fe3O4-Ag nanoparticles synthesized by the solvothermal method were studied in dependence on the duration of the thermolysis process (3, 6, and 8 h). X-ray diffraction, transmission electron microscopy, and energy-dispersive spectroscopy measurements showed that the morphology of nanoparticles changed strongly as the duration of thermolysis increased. At 6 and 8 h duration, Fe3O4 nanocrystals grow and assemble into porous spherical globules with an Ag core (samples 2 and 3). These samples demonstrate high magnetization value and very low coercivity. The adsorption capacity of nanoparticles was studied with respect to two organic dyes: cationic methylene blue (MB) and anionic Congo red (CR). The particles showed preferential adsorption of the cationic dye. High catalytic activity towards four dyes: MB, methyl orange (MO), CR, and Rhodamine C (RhC) at the presence of NaBH4 is the remarkable property of these samples. The rate constant of the catalytic reaction was 1.4 min−1. Simultaneous exposure of CR and MO dyes to nanoparticles and NaBH4 caused their irreversible 100 % degradation while in the case of MB and RhC, a transition to their leuco form occurred.

Аннотация:
The polarized optical absorption spectra in the region of a series of the f–f transitions of Nd3+ ions in the Ho0.75Nd0.25Fe3(BO3)4, Nd0.5Gd0.5Fe3(BO3)4, and NdFe3(BO3)4 crystals at 90 K have been compared. The spectral features related to the difference in the local environment of Nd3+ ions in these crystals have been established. In the region of the transition 4I9/2 → 4G5/2 + 2G7/2 of Nd3+ ions in the Ho0.75Nd0.25Fe3(BO3)4 crystal, the appearance of some absorption lines at the structural transition R32 → P3121 around ~200 K due to the local symmetry variation has been found. The intensity of these lines smoothly increases with a decrease in temperature from the transition point. The temperature dependence of the lattice parameters of the Ho0.75Nd0.25Fe3(BO3)4 crystal has been measured. It has been found that, at the transition temperature, the lattice parameter a changes stepwise, which is indicative of the occurrence of a first-order phase transition. The lattice parameter c changes smoothly.

Аннотация:
The morphology, structure, and magnetic properties of Fe3O4 and Fe3O4@C nanoparticles, as well their effectiveness for organic dye adsorption and targeted destruction of carcinoma cells, were studied. The nanoparticles exhibited a high magnetic saturation value (79.4 and 63.8 emu/g, correspondingly) to facilitate magnetic separation. It has been shown that surface properties play a key role in the adsorption process. Both types of organic dyes—cationic (Rhodomine C) and anionic (Congo Red and Eosine)—were well adsorbed by the Fe3O4 nanoparticles’ surface, and the adsorption process was described by the polymolecular adsorption model with a maximum adsorption capacity of 58, 22, and 14 mg/g for Congo Red, Eosine, and Rhodomine C, correspondingly. In this case, the kinetic data were described well by the pseudo-first-order model. Carbon-coated particles selectively adsorbed only cationic dyes, and the adsorption process for Methylene Blue was described by the Freundlich model, with a maximum adsorption capacity of 14 mg/g. For the case of Rhodomine C, the adsorption isotherm has a polymolecular character with a maximum adsorption capacity of 34 mg/g. To realize the targeted destruction of the carcinoma cells, the Fe3O4@C nanoparticles were functionalized with aptamers, and an experiment on the Ehrlich ascetic carcinoma cells’ destruction was carried out successively using a low-frequency alternating magnetic field. The number of cells destroyed as a result of their interaction with Fe3O4@C nanoparticles in an alternating magnetic field was 27%, compared with the number of naturally dead control cells of 6%.

Аннотация:
Magnetization dependences of CoxZnl1 – xFe2O4 nanoparticles (x = 0, 0.1, 0.2, 0.3, 0.4, 0.5) synthesized with the citrate precursor technique on an external magnetic field and temperature are presented. Ferrimagnetic order in nanoparticles with x ≥ 0.2 appeared at temperatures, T, exceeding room temperature, and in nanoparticles with x = 0 and 0.1 at T near 100 K. The saturation magnetization, Ms, remnant magnetization, Mr, and the coercive force, Hc, increase with x increase and the temperature decrease. Ms reached very high value: Ms of NPs with x = 0.5 equals to 106.6 emu/g at 100 K while, according to the literature data, Ms of stoichiometric bulk Co ferrite equals to 90 emu/g at 4.2 K. Correlations between concentration dependences of magnetic and electric properties has been revealed and explained qualitatively.

Аннотация:
Tuning optical or magnetic properties of nanoparticles, by addition of impurities, for specific applications is usually achieved at the cost of band gap and work function reduction. Additionally, conventional strategies to develop nanoparticles with a large band gap also encounter problems of phase separation and poor crystallinity at high alloying degree. Addressing the aforementioned trade-offs, here we report Ni–Zn nanoferrites with energy band gap (Eg) of ≈3.20 eV and a work function of ≈5.88 eV. While changes in the magnetoplasmonic properties of the Ni–Zn ferrite were successfully achieved with the incorporation of bismuth ions at different concentrations, there was no alteration of the band gap and work function in the developed Ni–Zn ferrite. This suggests that with the addition of minute impurities to ferrites, independent of their changes in the band gap and work function, one can tune their magnetic and optical properties, which is desired in a wide range of applications such as nanobiosensing, nanoparticle based catalysis, and renewable energy generation using nanotechnology.

Аннотация:
Nanoparticles of Co1–xMgxFe2O4 with x equal to 0, 0.2, 0.4, 0.6, 0.8 and 1.0 have been synthesized. For all values of x, they are nanocrystals with a cobalt ferrite structure and an average linear size (56 ± 3) nm. Based on the analysis of the Mossbauer effect spectra, the Co2+ ions were shown to occupy only octahedral positions at all values of x. The experimentally obtained dependence of the nanoparticles magnetization on x corresponds to the dependence calculated using the Mossbauer effect data, except for the sample with x = 1.0. The effective magnetic anisotropy constant estimated for 0 K from the analysis of the coercive force temperature dependences decreases from 5.27 × 106 at x = 0 to 1.29 × 106 erg/cm3 at x = 0.8 and drops sharply to 4 × 104 erg/cm3 at x = 1.0

Аннотация:
The effect of surfactants on the structure, morphology, and magnetic properties of FexSy iron-sulfide nanoparticles synthesized by thermal decomposition is studied. Oleylamine, hexadecylamine, and octadecylamine are used as surfactants. It is established by X-ray and electron-diffraction analysis combined with Mossbauer spectroscopy that, in samples 1 and 2 prepared using oleylamine and hexadecylamine, respectively, the Fe3S4 greigite phase dominates, with an inverse spinel structure isostructural to the iron oxide Fe3O4 magnetite with minor Fe9S11 impurities. Deviations in the distribution of iron cations over the tetrahedral and octahedral sites relative to the bulk greigite crystals are observed. The nanoparticles synthesized using octadecylamine (sample 3) are found to be multiphase with a greigite fraction of ~20%. In all three cases, as showed the results of transmission electron microscopy and Fourier transform infrared spectroscopy together with thermogravimetry analysis, the magnetic nanoparticles have an organic shell chemically bonded to their magnetic core, which prevents the agglomeration of the particles. This shell is much more massive in samples 2 and 3. The magnetization values for samples 1 and 2 are similar to those of greigite nanoparticles reported in publications, while the magnetization of sample 3 is several times lower, in accordance with the greigite fraction in it. The combination of fairly high magnetization with a massive organic shell allows one to consider hexadecylamine to be a promising surfactant for the synthesis of iron-sulfide nanoparticles protected from external impact and agglomeration.

Аннотация:
The linear birefringence induced by the electric field was first detected in a TmAl3(BO3)4 single crystal. The electric field dependence of the birefringence was investigated. The estimation of the electro-optical coefficient of the material gives ≈1.5×10−10 cm/V for a wavelength 632.8 nm.

Аннотация:
Polarized absorption spectra and magnetic circular dichroism (MCD) spectra of Nd0.5Gd0.5Fe3(BO3)4 single crystal were measured in the range of 10000 - 21000 cm-1. The absorption spectra were studied as a function of temperature in the range of 2 - 293 K and as a function of magnetic field 0 - 65 kOe at 2 K. The excited 4f states of the Nd3+ ion were identified in terms of the irreducible representations and in terms of |J,+-MJ> wave functions of the free atom. The changes of the Lande factor during f-f transitions and the exchange splitting of the ground and excited states were determined. It was found out that the selection rules for electron transitions substantially changed in the magnetically ordered state of the crystal. They are different for the different transitions and they strongly depend on the orientation of the Fe sublattice magnetic moment relative to the light polarization. It was revealed that the local magnetic properties in the vicinity of the excited Nd3+ ion substantially depended on its state. In particular, in some excited states a weak ferromagnetic moment appears, the field induced reorientation magnetic transitions occur and the changes of the local magnetic anisotropy type take place. In some excited states the nonequivalent Nd3+ centers were found out.

Аннотация:
Planar and vertical hybrid structures, which combine ferromagnetic and semiconductor layers are essential for implementation and study of spin transport phenomena in semiconductors, which is crucial for the advancement and development of spintronics. We have developed approaches for the synthesis of Fe3 + xSi1 – x epitaxial thin films and demonstrated the spin accumulation effect in multiterminal devices based on Fe3 + xSi1 – x/Si. Fe3 + xSi1 – x/Ge/Fe3Si and Fe3 + xSi1 – x/Ge/Mn5Ge3 multilayer hybrid structures were synthesized on a Si(111) substrate, study of their structural, magnetic and transport properties were performed. The effect of synthesis conditions on the growth of epitaxial structures and on their magnetic and transport properties was discussed. The results obtained may prove valuable in the development and fabrication of spintronic devices.

Аннотация:
The giant natural optical activity of vibronic replicas of the f–f5/8 → 5F2 transition in HoAl3(BO3)4 is observed. It exceeds the optical activity related to purely electronic transitions by two orders of magnitude and corresponds to the almost complete circular polarization of the transitions. This effect is explained by the local distortions of the crystal in the excited electronic state, which lead to the mixing of electron and vibrational wavefunctions and, as a consequence, to the delocalization of the vibronic wavefunction and the enhancement of spatial dispersion, which is responsible for the optical activity.
