Аннотация: Ni0.2Zn0.8Fe2O4 spinel nanoparticles have been synthesized by combustion method. Average particles size varies from 15.5 to 50.0 nm depending on annealing temperature. Correlations between particles size and magnetic and magneto-optical properties are investigated. Magnetization dependences on temperature and external magnetic field correspond to the sum of paramagnetic and superparamagnetic response. Critical size of single-domain transition is found to be 15.9 nm. Magnetic circular dichroism (MCD) studies of nickel zinc spinel are presented here for the first time. The features in magnetic circular dichroism spectrum are assigned to the one-ion d-d transitions in Fe3+ and Ni2+ ions, as well to the intersublattice and intervalence charge transfer transitions. The MCD spectrum rearrangement was revealed with the change of the nanoparticles size. © 2016 Elsevier B.V. All rights reserved.

magnetic circular dichroism (MCD) -- MCD spectroscopy -- absorption spectroscopy of oil
Аннотация: Optical and magneto-optical properties of solutions of crude oil of different origin (i.e., taken from different fields) are studied in the visible and near-UV region of optical emission. Magnetic circular dichroism (MCD) spectra of oil are obtained in the vicinity of wavelengths of ~410 nm, 533 nm, and 576 nm. It is demonstrated that the intensity of the MCD signal depends on the origin of crude oil, and it is proportional to the oil concentration in the solution. The comparison of the magneto-optical spectroscopy data with the chemical composition of samples allows us to conclude that the observed magneto-optical activity is determined by the presence of VO2+ complexes in the oil samples studied. The revealed magneto-optical activity of conventional oil can form a basis of a new method for the analysis of the composition and properties of oil of different origin.

Аннотация: Ni-C nanoparticles powder (NP) was synthesized using high-temperature pyrolysis of nickel nitrate in an organic solvent. The NP was characterized by transmission electron microscopy (TEM), energy dispersive x-ray spectroscopy (EDXS) and selected-area electron diffraction (SAED). Structural characterization of the samples confirmed the formation of small, medium and large Ni nanoparticles with face-centered cubic structure (fcc) and enlarged lattice parameter. Magnetic circular dichroism (MCD) of samples with different mean particle sizes showed a red shift with decrease of mean particle size. © Siberian Federal University. All rights reserved.
Порошок наночастиц Ni-C был синтезирован с помощью высокотемпературного пиролиза нитрата никеля в органическом растворителе. Наночастицы были исследованы с помощью просвечивающей электронной микроскопии, энергодисперсионной рентгеновской спектроскопии и дифракции электронов выбранной зоны. Структурная характеризация образцов подтвердила образование маленьких, средних и больших наночастиц никеля с гранецентрированной кубической структурой и увеличенным параметром решётки. Магнитный круговой дихроизм образцов с различными средними размерами частиц показал красное смещение при уменьшении среднего размера частиц.

Greigite -- Thermal decomposition -- Surfactants -- Mössbauer effect -- FT-IR spectra -- Magnetic circular dichroism
Аннотация: Greigite (Fe3S4) nanoparticles (NPs) were fabricated by the thermal decomposition method using two different surfactants: oleylamine (OLA) and 1-hexadecylamine (HDA). In both cases, the synthesized NPs were characterized as the Fe3S4 nanocrystals with minor inclusions of Fe9S11 phase. FT-IR spectroscopy and thermo-gravimetric analysis allow concluding about OLA or HDA shells covering magnetic core of NPs. Mossbauer spectra has revealed deviations of iron ions distribution among crystal positions from that presented in literature for pure greigite. In accordance with these deviations, the pronounce changes are observed in the magnetic circular dichroism (MCD) spectra which manifest themselves as the spectrum shift to higher energies of electromagnetic waves and redistribution of the MCD maximum intensities. These effects are associated with a change in the density of electronic states in the samples due to the redistribution of iron ions between octahedral and tetrahedral positions in nanocrystals under the influence of surfactants.

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.
