    Magnetic, structural, and electronic properties of iron sulfide Fe3S4 nanoparticles synthesized by the polyol mediated process / I. S. Lyubutin [et al.] // J. Nanopart. Res. - 2013. - Vol. 15. - P. 1397DOI 10.1007/s11051-012-1397-0
   Перевод заглавия: Магнитные, структурные и электронные свойства наночастиц сульфида железа Fe3S4, полученных полиол-синтезом
Аннотация: Iron sulfide nanoparticles Fe3S4 with the spinel-type crystal structure were synthesized by the polyol mediated process. The particle size depends on preparation conditions and varies from 9 to 20 nm. Mössbauer data have revealed that the dominating fraction of iron ions in the 9-nm sample is in the high-spin ferric state. This implies an occurrence of the cation vacancies in nonstoichiometric greigite. The stoichiometric phase of greigite Fe3S4 dominates in the 18-nm-size nanoparticles. Magnetic measurements have shown a ferrimagnetic behavior of all samples at temperatures between 78 and 300 K. The estimated value of magnetic moment of the stoichiometric greigite nanoparticles is about 3.5 μB per Fe3S4 unit. The Mössbauer spectra indicate a superparamagnetic behavior of small particles, and some fraction of superparamagnetic phase is observed in all samples synthesized which may be caused by the particle size distribution. The blocking temperatures of T B ≈ 230 and 250 K are estimated for the 9 and 14 nm particles, respectively. The Mössbauer parameters indicate a great degree of covalency in the Fe–S bonds and support the fast electron Fe3+ ⇆ Fe2+ exchange in the B-sites of greigite. An absence of the Verwey transition at temperatures between 90 and 295 K is established supporting a semimetal type of conductivity. The temperature and magnetic field dependences of the magnetic circular dichroism (MCD) of optical spectra were measured in Fe3S4 for the first time. The spectra differ substantially from that of the isostructural oxide Fe3O4. It is supposed that the MCD spectra of greigite nanoparticles result from the collective electron excitations in a wide band with superimposed peaks of the d–d transitions in Fe ions.

Аннотация: A novel miniature stripline resonator performed on a double-layer suspended substrate and bandpass filters (BPFs) based on it are proposed. The filters have wide stopband with high attenuation. A fifth-order BPF has been designed and fabricated. The filter stopband at level of −100 dB extends up to the frequency that exceeds the passband center frequency by factor of 10. It is shown that miniature filters based on the proposed resonator could be effectively fabricated by low temperature cofired ceramics technology.

Аннотация: Resonator of a new type is described, which is formed by two coaxial conductors applied onto the internal and external surfaces of a ceramic tube arranged in a metal case. An equation for the resonant frequencies is derived. In comparison to a standard coaxial quarter-wave resonator, the proposed device has a shorter length and manifold increased ratio of frequencies of the second resonance to the first resonance. The new resonator can be used for the creation of bandpass filters with ultra-wide stopband. The frequency response of a working prototype four-resonator filter is presented, in which the stopband at a -90 dB level extends up to a frequency that is 47 times greater than the central frequency of the passband.

strong electronic correlations -- magnetic mechanism of pairing -- quantum phase transitions -- electronic structure -- Hubbard operators -- cuprates
Аннотация: The multielectron LDA+GTB approach has been developed to calculate electronic structure of strongly correlated cuprates. At low energies the effective Hamiltonian of the t- t’- t”- t﬩-J*-J﬩ -model has been derived with parameters coming from the ab initio calculation for LSCO. The electronic structure of LSCO has been calculated self-consistently with the short-range antiferromagnetic order for various doping level. Two Lifshitz-type quantum phase transitions with Fermi surface topology changes have been found at dopings x(c1) = 0.15 and x(c2) = 0.24. Its effect on normal and superconducting properties has been calculated. The interatomic ex change parameter and its pressure dependence has been calculated within LDA+GTB scheme. The magnetic mechanisms of d-wave pairing induced by static and dynamical spin correlations are discussed. Simultaneous treatment of magnetic and phonon pairing results in the conclusion that both contributions are of the same order. For two layer cuprates like YBCO the interlayer hopping and exchange effects on the electronic structure and doping dependence of Tc is discussed as well as the Coulomb interaction induced mechanism of pairing.

Аннотация: We report giant magnetoresistance (MR) effect that appears under the influence of optical radiation in common planar device built on Fe/SiO2/p-Si hybrid structure. Our device is made of two Schottky diodes connected to each other by the silicon substrate. Photo-induced MR is positive and the MR ratio reaches the values in excess of 10(4)%. The main peculiarity of the MR behavior is its strong dependence on the magnitude and the sign of the bias current across the device and, most surprisingly, upon polarity of the magnetic field. To explain such unexpected behavior of the MR, one needs to take into account contribution of several physical mechanisms. The main contribution comes from the existence of localized interface states at the SiO2/p-Si interface, which provide the spots for the photo-current conduction by virtue of the sequential tunneling through them or thermal generation and optical excitation of mobile charges. External magnetic field changes the probability of these processes due to its effect on the energy states of the conduction centers. Two possible mechanisms that may be responsible for the observed dependence of magneto-resistance on the field polarity are discussed: the effect of the Lorentz force on moving carriers and spin splitting of electrons moving in the electrostatic potential gradient (Rashba effect). The most significant observation, in our opinion, is that the observed MR effect is seen exclusively in the subsystem of minority carriers transferred into non-equilibrium state by optical excitation. We suggest that building such magneto-sensitive devices based on this mechanism may set a stage for new types of spintronic devices to emerge. (C) 2013 AIP Publishing LLC.

Аннотация: The infrared absorption spectra of the oxyfluoride Rb2KMoO3F3 have been measured in the frequency range corresponding to stretching vibrations of the Mo-O anion octahedron with the purpose of clarifying their role in the phase transition. A semi-empirical calculation of two possible configurations of quasioctahedral MoO3F3 groups has been performed. The results of the investigations have demonstrated that some octahedra in the crystal structure change the local symmetry from C (3v) to C (2v) due to the phase transition (T = 197 K).

Аннотация: The molecular structure of 1-phenyl-2-nitroguanidine is nonplanar, but contains two almost planar fragments: nitroguanyl and phenyl groups. Unlike previously studied nitroguanidines, in 1-phenyl-2- nitroguanidine, the nitro group is turned to the secondary amino group. However, the structural parameters of the nitroguanyl group are little different from those of nitroguanidine and its alkyl derivatives. In the benzene ring, the symmetry in the geometric parameters is not observed, which is explained by the intermolecular interaction with the neighboring molecule.

Аннотация: The behaviour of the optical absorption bands of NaMnCl//3 is experimentally studied in the region of the **6A//1//g to **4A//1//g, **4E//g(**4G) transition of the Mn**2** plus ion in the temperature range 1. 8 to 20 K and in magnetic fields up to 20 T. Exciton and its 'hot' magnon sidebands are observed in the spectrum. The anomalous temperature dependence of the exciton-magnon bands intensity is explained by participation of magnons with wave vector K does not equal 0 in absorption. The low energy exciton-magnon band is supposed to be due to simultaneous creation of an exciton and annihilation of three thermally created magnons.

Аннотация: Ceramic volumetric composites xLa(0.7)Pb(0.3)MnO(3)-(1-x)PbTiO3 (x = 0.18 and 0.85) were prepared. X-ray investigations have shown that rather low sintering temperature (800 degrees C) has allowed us to avoid the reaction and interdiffusion between two initial phases. Heat capacity, thermal expansion, and intensive magnetocaloric effect were measured in a wide temperature range. The sample composition has a low influence on temperatures of the ferromagnetic and ferroelectric phase transitions in composites. Electro- and barocaloric effects were determined by analysis in the framework of thermodynamic theory, electric equation of state, Maxwell relationships, and entropy-temperature-pressure phase diagram. Multicaloric efficiency of composites is discussed and compared with that of initial La0.7Pb0.3MnO3 and PbTiO3 compounds. Variation of a relationship between components can significantly increase both barocaloric and magnetocaloric efficiency of compositional material due to the mechanical stress appearing between grains of different ferroic phases under magnetic field.

   Перевод заглавия: Планарный полосно-пропускающий фильтр со 100-дБ подавлением до десятикратной частоты полосы пропускания
Аннотация: This paper proposes a miniature microwave bandpass filter. It comprises quasi-lumped suspended substrate stripline resonators of a new type. Their common substrate consists of two contiguous dielectric layers. Every resonator in the filter has three parallel strip conductors. Two of them are placed on the outer substrate surfaces and the rest is placed inside the substrate. The filter of the sixth order was designed with the use of special optimization rules that are universal for all resonator filters. The substrate of the fabricated filter was made of RT/Duroid 5880 (εr = 2.2, tan δ = 0.002) with thickness of 0.127 mm. It has dimensions of 12mm x 45:5 mm. The measured passband has a center frequency of 1.01 GHz, 3-dB fractional bandwidth of 11%, and minimum insertion loss of 1.4 dB. The 100-dB upper stopband extends up to 10.5 GHz.

Аннотация: The results of NMR studies of film structures in a cobalt-germanium system as a function of the cobalt layer thickness are presented. Two phases of cobalt, one is a face-centered cubic phase and the other is presumably a Co-Ge alloy with a weakly ferromagnetic order, have been found to exist. A "dead" layer no more than 2 nm in thickness is formed at the interface.

Аннотация: The effect of multiple reflection in the process of electron transport on the current-voltage characteristics of an adsorbed magnetic atom with single-ion anisotropy has been investigated. All orders of the perturbation theory with respect to the parameter of coupling between the contacts and the multilevel impurity have been taken into account by the Keldysh diagram technique with the use of Hubbard operators. It has been shown that the current-voltage characteristics of the system in a strongly nonequilibrium regime contains regions of negative differential conductance. The ways of enhancing this effect are discussed.

Аннотация: Initial growth stages of manganese films on the Si(100)2 × 1 surface at room temperature have been investigated using high-energy-resolution photoelectron spectroscopy, and the dynamics of the variation in their phase composition and electronic structure with the coverage growth has been revealed. It has been shown that the interfacial manganese silicide and the film of the solid solution of silicon in manganese are sequentially formed under these conditions on the silicon surface. The growth of the metal manganese film starts after the deposition of ~0.9 nm Mn. Segregation of silicon on the film surface is observed in the range of coverages up to 1.6 nm Mn.

Аннотация: Raman spectra of light are obtained for HoFe3(BO3)(4) and HoAl3(BO3)(4) crystals at various temperatures and are used for determining the frequencies of crystal lattice vibrations at the center of the Brillouin zone. It is also found that the HoFe3(BO3)(4) crystal exhibits a phase transition at T (c) a parts per thousand 366 K. The magnetoelectric effect in the paramagnetic phase of these compounds is studied experimentally. The lattice vibration frequencies, elastic and piezoelectric moduli, Born dynamic charges, and the high-frequency permittivity are calculated using the density functional method. A peculiar behavior of the transverse acoustic vibration branch is observed in the I" - Z direction of the Brillouin zone of the HoFe3(BO3)(4) crystal. The electric polarization induced by an external field is estimated using the calculated values of piezoelectric moduli and experimental values of magnetostriction.
Спектры КР света получены для HoFe3 (BO3) 4 и HoAl3 (BO3) 4 кристаллы при различных температурах и используются для определения частоты колебаний кристаллической решетки в центре зоны Бриллюэна. Также обнаружено, что HoFe3 (BO3) 4 демонстрирует фазовый переход при Tc ≈ 366 К. Магнитоэлектрический эффект в парамагнитной фазе этих соединений экспериментально исследован. Частоты колебаний решетки, упругие и пьезоэлектрические модули, Борновские динамические заряды, и высокочастотная проницаемость рассчитываются с использованием метода функционала плотности. Своеобразное поведение поперечной ветви акустических колебаний наблюдается в направлении Γ Z зоны Бриллюэна в HoFe3 (BO3) 4.Электрическая поляризация индуцированная внешним полем оценивается с помощью расчетные значения пьезомодулей и экспериментальных значений магнитострикции.
