f-f transitions -- Ho3+ ion -- Excited states -- Local properties
Аннотация: We measured absorption spectra of transitions 5I8 → 5F2, 5F3 in Ho3+ ion in the HoFe3(BO3)4 single crystal at temperature 2 K as a function of magnetic field 0–65 kOe directed along a and c axes. The spectra were decomposed to the Lorentz shape components and magnetic field dependences of their parameters: position, intensity and line width, were obtained. Substantial difference between dependences of the energy and intensity of the transitions on magnetic field was revealed. So, the abrupt changes of the electron transition energies were mainly observed at the reorientation magnetic phase transitions in the crystal. A number of singularities in the magnetic field dependences of the electron transition intensities were revealed both at the reorientation transitions and outside of them. The singularities in the average intensities of transitions into multiplets at the reorientation magnetic transitions are due to the changes of the odd part of the crystal field, responsible for the allowance of f-f transitions, and also are due to the changes of the magnetic state. The singularities in behavior of intensity of each separate transition are due to the local even distortions in the excited states, which mix the electron states.

spin accumulation -- interface states -- hybrid structures -- Hanle effect -- iron silicide
Аннотация: Spin accumulation effect in Fe3Si/p-Si structure with low boron doped silicon substrate was found. Calculated spin lifetimes are comparable with results reported earlier but for structures with highly doped semiconductors (SC) with or without a tunnel barrier introduced between the SC and ferromagnet (FM). Electrical characterization of a prepared Fe3Si/p-Si diode allowed the determination of possible reasons for the pronounced spin signal. Analysis of the forward bias I-V curve revealed a Schottky barrier at the Fe3Si/p-Si interface with a height of φBp = 0.57 eV. Then, using impedance spectroscopy, we observed interface states localized in the band gap of silicon with energy of E LS = 40 meV. Such states most probably cause the observed spin signal. We believe that in our experiment, spin-dependent hole extraction was performed via the interface states resulting in the minority spin accumulation in the silicon valence band. The observed effect paves the way to the development of different spintronic devices based on FM/SC structures without dielectric tunneling barriers.

Magnetoimpedance -- Spintronics -- Metal/insulator/semiconductor structures -- Nanosized semiconductors
Аннотация: This article presents the results of a study of the transport properties of metal/insulator/semiconductor (MIS) hybrid structures in alternating current (ac) mode. We prepared a series of samples with different layers of metal, insulator, and semiconductor. We prepared a series of samples with different layers of metal, insulator and semiconductor. Ferromagnetic Fe and non-magnetic Cu and Mn were chosen as metals, the insulators were SiO2 and Al2O3, and n- and p-type Si substrates were used as semiconductors. Temperature dependence of the real part of the impedance showed peculiar peaks below 40К for different combinations of metals, insulators and semiconductors. For all samples the effect of the magnetic field on the transport properties was studied. At low temperatures, the magnetic field shifts peaks toward higher temperatures. Metal magnetic state does not significantly affect this phenomenon. Changing the type of the insulator and its thickness also did not cause any significant effect. However, the effect was observed for samples with different composition. Moreover, the type of conductivity of the substrate, as well as the type of metal, determines the value of magnetoimpedance. The main role in the magnetoimpedance effect is played by recharge of the energy states localized at the insulator/semiconductor interface. This mechanism allows obtaining a MI effect even in “nonmagnetic” MIS structures; magnetoimpedance can be either positive or negative, depending on temperature and frequency. We suggest that the observed ac magnetotransport phenomena could be used for creating magnetic field sensors, working on new principles.

Substituted rare earth cobalt oxides -- Thermoelectric oxide materials -- Ordered and disordered states
Аннотация: Temperature dependences of the electrical resistivity and Seebeck coefficient of the Re0.2Sr0.8CoO3‒δ (Re = Gd, Dy) complex cobalt oxides in the temperature range of 300 – 800 K have been investigated. The effects of ordering in the cation and anion sublattices on the thermoelectric properties has been examined and their comparative analysis has been made. It was found that, in the investigated temperature range, the thermoelectric power factor of the ordered compounds significantly exceeds the analogous parameter of the disordered samples. The temperature dependence of the electrical resistivity was shown to obey the activation law. As the temperature increases, the samples undergo a semiconductor-semiconductor electronic transition with a decrease in the activation energy. The thermoelectric properties of all the samples are shown to be stable in the investigated temperature range. The maximum thermoelectric power factor of the ordered Dy0.2Sr0.8CoO2.67 cobaltite at a temperature of 360 K has been obtained; it amounts to 0.23 µW/(cm·K2), which is a good parameter for this class of materials.

Аннотация: Spectral peculiarities of the structure consisting of a photonic crystal coated with a nanocomposite (NC) have been investigated. The NC used contains spheroidal nanoparticles with a dielectric core and a metallic shell, which are uniformly dispersed in a transparent matrix. The spectral manifestation of the observed Tamm plasmon polariton (TPP) and Fabry-Perot mode has been examined. A significant polarization sensitivity of the spectra upon variation in the nanoparticle shape has been demonstrated. The dispersion curves presented for the TPP and Fabry-Perot mode are shown to be in good agreement with the spectra obtained by the transfer matrix method.

Такие структуры были найдены во многих растениях. При состыковке двух последовательно соединённых подрешёток с разными периодами отмечается увеличение амплитуды электромагнитного поля и плотности фотонных состояний внутри структуры и их изменение в зависимости от асимметрии толщин подрешёток.
Calculations were performed using the transfer matrix of one-dimensional photonic crystals with low contrast and asymmetric structures of different periods. Such structures have been found in many plants. When joining two successively connected sublattices with different periods, an increase is observed in the amplitude of the electromagnetic field and the density of photon states inside the structure, and their change depends on the asymmetry of the thickness of the sublattices.

Аннотация: We consider nonlinear effects in scattering of light by a periodic structure supporting optical bound states in the continuum. In the spectral vicinity of the bound states the scattered electromagnetic field is resonantly enhanced triggering optical bistability. Using coupled mode approach we derive a nonlinear equation for the amplitude of the resonant mode associated with the bound state. We show that such an equation for the isolated resonance can be easily solved yielding bistable solutions which are in quantitative agreement with the full-wave solutions of Maxwell's equations. The coupled mode approach allowed us to cast the the problem into the form of a driven nonlinear oscillator and analyze the onset of bistability under variation of the incident wave. The results presented drastically simplify the analysis nonlinear Maxwell's equations and, thus, can be instrumental in engineering optical response via bound states in the continuum.

Аннотация: In this work we experimentally observe a symmetry protected optical bound state in the continuum (BIC) with zero angular momentum in 1D array of ceramic disks at GHz frequencies. We analyze the dependence of Q factor of BIC on the number of the disks and the level of the material losses. We confirmed theoretical prediction about quadratic growth of the Q factor with the number of the disks and its following saturation due to material losses.

Аннотация: We trace the Q factor of the resonant modes which are limited to bound states in the continuum (BICs) for N=∞ in the finite array of N dielectric spheres and disks. For the symmetry-protected BICs we observe the quadratic dependence of the Q factor on N for high-refractive-index particles, while for low-refractive-index particles there is an interplay between the quadratic and cubic dependencies. The Q factor of accidental BICs grows cubically with N. We show that a plane wave can excite these quasi-BICs for tuning of the angle of incidence.

Cholesteric liquid crystal -- Optical Tamm states -- Localization -- Transmission spectrum -- Optical devices
Аннотация: The modes formed by two coupled chiral optical Tamm states localized at the interfaces between a photonic cholesteric liquid crystal conjugated with polarization-preserving anisotropic mirrors have been analytically and numerically investigated. These modes are only excited at the diffracting polarization of incident light. As the cholesteric layer thickness decreases, the spectral splitting of the localized state frequency is predicted. The splitting value depends on the crystal layer thickness. At the nondiffracting circular polarization, the localized modes are not excited, and the system becomes similar to the Fabry-Perot cavity containing an anisotropic helical structure.

Аннотация: The correlation between the kinetic stability of molecules against temperature and variations in their geometric structure under optical excitation is investigated by the example of different organic pheromone molecules sensitive to temperature or ultraviolet radiation using the density functional theory. The kinetic stability is determined by the previously developed method based on the calculation of the probability of extension of any structural bond by a value exceeding the limit value Lмах corresponding to the breaking of the bond under temperature excitation. The kinetic stability calculation only requires the eigenfrequencies and vibrational mode vectors in the molecule ground state to be calculated, without determining the transition states. The weakest bonds in molecules determined by the kinetic stability method are compared with the bond length variations in molecules in the excited state upon absorption of light by a molecule. Good agreement between the results obtained is demonstrated and the difference between them is discussed. The universality of formulations within both approaches used to estimate the stability of different pheromone molecules containing strained cycles and conjugated, double, and single bonds allows these approaches to be applied for studying other molecules.

Аннотация: We consider an optical response induced by bound states in the continuum (BICs) in arrays of dielectric spheres. By combining the quasi-mode expansion technique with coupled mode theory (CMT), we put forward a theory of the optical response by high-Q resonance surrounding BICs in momentum space. The central results are analytical expressions for the CMT parameters, which can be easily calculated from the eigenfrequencies and eigenvectors of the interaction matrix of the scattering systems. The results obtained are verified in comparison against exact numerical solutions to demonstrate that the CMT approximation is capable of reproducing Fano features in the spectral vicinity of the BIC. Based on the quasi-mode expansion technique, we derived the asymptotic scaling law for the CMT parameters in the vicinity of the Γ-point. It is rigorously demonstrated that the linewidth in the CMT approximation exhibits different asymptotic behavior depending on the symmetry of the BIC.

Аннотация: In this work we experimentally observe a symmetry protected optical bound state in the continuum(BIC) with zero angular momentum in 1D array of ceramic disks at GHz frequencies. We analyze the dependence of Q factor of BIC on the number of the disks and the level of the material losses. We confirmed theoretical prediction about quadratic growth of the Q factor with the number of the disks and its following saturation due to material losses.

Аннотация: We consider acoustic wave transmission in a non-axisymmetric waveguide composed of a cylindrical resonator of radius R and length L and two cylindrical waveguides of radius rR. The center lines of the waveguides are shifted relative to the center line of the resonator by a distance r0 and relative to each other by an azimuthal angle Δϕ. Under variation of L and fixed Δϕ we find bound states in the continuum (trapped modes) due to full destructive interference of resonant modes leaking into waveguides. Rotation by the angle Δϕ brings complex phases into the coupling strengths of the resonator eigenmodes with propagating modes of the waveguides. As the result interference of neighboring resonances strongly depends on rotation of the waveguide introducing novel way for tuning Fano resonances. In turn rotation of the input waveguide strongly affect the acoustic transmission through the resonator imitating a faucet in wave transmission. Under variation of Δϕ and fixed L we find symmetry protected trapped modes. For Δϕ≠0 these trapped modes contribute to the scattering function supporting high vortical acoustic intensity spinning inside the resonator.
