Ключевые слова (''Своб.индексиров.''): single-chain magnets--light-induced spin crossover--magnetic susceptibility--quantum phase transitions
Аннотация: An exact solution for a generalized Ising model describing single-chain magnet {[FeIII(Tp*)(CN)3]2FeII(bpmh)}·2H2O with alternating high-spin and low-spin iron ions and double-zigzag magnetic topology has been calculated making use of the transfer-matrix technique. The introduction of a statistical ensemble taking into account the presence of iron ions with high-spin (HS) and low-spin (LS) states made it possible to describe the modification of magnetic susceptibility under optical irradiation. It has been shown that joint implementation of iron ions with photoinduced magnetic states and non-magnetic intersite repulsion ions of these states is caused by the difference of the ionic radii of HSFeIIHSFeII and LSFeIILSFeII leads to the quantum phase transitions in the system.

Ключевые слова (''Своб.индексиров.''): quantum magnets--spin wave theory--strong single-ion anisotropy
Аннотация: We have developed the spin wave theory of Heisenberg magnets with strong single-ion anisotropy of arbitrary symmetry with two and more sublattices. Using this approach, the low-temperature magnetic properties of the single-chain magnet catena- [FeII(ClO4)2FeIII(bpca)2](ClO4) with four sublattices and twisting mutually orthogonal easy plane have been calculated. It has been shown that the modulation of the easy planes directions creates on the one hand the low-temperature excitation spectrum similar to the one of the Ising models, and on the other hand strong spin fluctuations.

Аннотация: New law of the approach to magnetic saturation is proposed based on scaling in ferromagnets with random magnetic anisotropy. This law is consistent with the known laws derived within perturbation theory in extreme cases, but it describes the transition mode between the power-low asymptotic regimes better. The improved law is proper for reliable fitting the approach magnetization to saturation in nanocrystalline and amorphous ferromagnets. © 2017 Elsevier B.V.

Ключевые слова (''Своб.индексиров.''): thmn 12 -type phase--permanent magnets--rare earth-lean magnets
Аннотация: Rapidly increasing demand for high-energy permanent magnets and volatility of the rear-earth market encourage a search of hard magnetic materials that can compete with those based on the Nd2Fe14B phase. Sm-Fe compounds with the ThMn12-type crystal structure are considered as promising candidates for it. However, their synthesis and achievement of theoretically predicted magnetic properties are still challenging tasks that have not been solved yet. This paper addresses this problem. Its aim was to synthesize and to study magnetic properties of the (Sm0.9Zr0.1)Fe11Ti compound with ThMn12-type structure. Initially amorphous alloy was obtained by melt spinning and its subsequent heat treatments were performed. Structural and phase transformations of the (Sm0.9Zr0.1)Fe11Ti alloy with annealing temperatures were studied along with magnetic properties. For the optimally annealed alloy features of magnetization reversal were discussed and temperature dependences of coercivity and maximum energy product were obtained.

Ключевые слова (''Своб.индексиров.''): high-tc superconductors--ybco--foam--trapped fields--current flow
Аннотация: Superconducting foams of YBa2Cu3Oy (YBCO) are proposed as trapped field magnets or supermagnets. The foams with an open-porous structure are light-weight, mechanically strong and can be prepared in large sample sizes. The trapped field distributions were measured using a scanning Hall probe on various sides of an YBCO foam sample after field-cooling in a magnetic field of 0.5 T produced by a square Nd-Fe-B permanent magnet. The maximum trapped field (TF) measured is about 400 G (77 K) at the bottom of the sample. Several details of the TF distribution, the current flow and possible applicatons of such superconducting foam samples in space applications, e.g., as active elements in flux-pinning docking interfaces (FPDI) or as portable strong magnets to collect debris in space, are outlined.

Ключевые слова (''Своб.индексиров.''): high-power magnets--iron losses--magnetic parameters--magnetite iron--tailings--wet separation
Аннотация: Samples of all the tailings from enrichment processes at the Abagur plant operated by OAO Evrazruda are studied. The tailings are subjected to magnetic and chemical analysis, and the magnetic characteristics of the products are measured. The mean magnetite iron content in the tailings was about 0.9% in 2013. Experiments confirm that the main magnetite losses are associated with small classes and their poor magnetic properties. The losses of magnetite are reduced as the separation field is increased. At the plant, 45% of the barium–ferrite magnetic systems in the PBM 90/250 separators have been replaced by a system based on neodymium–iron–boron composites, with increase in the field from 111 to 175 kA/m. Modernization of the magnetic systems in all the separators at the Abagur plant is recommended. In thickening, the installation of separators for regeneration of the suspensions, with a field of 190 kA/m, is recommended. After reconstruction, the losses of magnetite iron at the plant may be reduced to 0.45–0.55%. © 2016, Allerton Press, Inc.

Аннотация: Specially picked up web-chamber is used for visualization of domain structure in hematite. An analysis of domain configuration shows, that domain structure of hematite in a basal plane represents multilayered structure which contains domains both in paralleled thickness and in the parallel basal planes. The temperature features of magnetic permeability and domain structures in Fe2O3:Ga crystals near the Morin transition are investigated. Observable changes of magnetic permeability and changes in domain structure confirm that transition from AFM to WFM occurs in the hematite with Ga impurity as transition of the first sort. Results of research of antiferromagnetic and weakly ferromagnetic resonances (AFMR and WFMR) in these compounds are presented.

Аннотация: Левитация постоянного магнита цилиндрической формы над высокотемпературным сверхпроводником, охлаждаемым жидким азотом, сопровождается спонтанными колебаниями, переходящими во вращение. Причиной вращения является неоднородность намагниченности магнита, вызванная градиентом температур вдоль вертикальной оси. Проведен эксперимент по левитации магнитов Nd–Fe–B над композитным высокотемпературным сверхпроводником. Результаты эксперимента подтверждают, что частота вращения зависит от намагниченности верхней и нижней половин магнита. Предложены способы контроля частоты вращения левитирующего магнита.Levitation of a cylindrical permanent magnet over a high-temperature superconductor cooled by liquid nitrogen can be accompanied by spontaneous oscillations and rotation. The reason for spontaneous rotation of the magnet is magnetization inhomogeneity induced by the temperature gradient. An experiment was carried out on the levitation of Nd–Fe–B magnets over a composite high-temperature superconductor. The experimental results confirm that the rotation frequency depends on the difference in the magnetization values in its upper and lower halves of the magnet. Methods for controlling the rotation frequency of a levitating magnet are proposed.

Аннотация: The effect of the magnetic correlators on the spin polaron superconducting phase is studied in terms of 2D Kondo lattice model. It is shown that hopping integrals are renormalized by the magnetic correlators and as a result the Tc phase diagram is changing significantly. By computation the effect of magnetic correlation functions on the concentration dependence of T c was analysed and their substantial role in description of doped antiferromagnets is demonstrated. The obtained phase diagram is in qualitative agreement with experimental data for temperature dependence of the superconducting phase transition with d-type symmetry in cuprates. © 2010 IOP Publishing Ltd.

Аннотация: The inertial dynamics of magnetization in a ferromagnet is investigated theoretically. The analytically derived dynamic response upon microwave excitation shows two peaks: ferromagnetic and nutation resonances. The exact analytical expressions of frequency and linewidth of the magnetic nutation resonance are deduced from the frequency-dependent susceptibility determined by the inertial Landau-Lifshitz-Gilbert equation. The study shows that the dependence of nutation linewidth on the Gilbert precession damping has a minimum, which becomes more expressive with increase of the applied magnetic field.

Аннотация: Magnets derived from inorganic materials (e.g., oxides, rare-earth–based, and intermetallic compounds) are key components of modern technological applications. Despite considerable success in a broad range of applications, these inorganic magnets suffer several drawbacks, including energetically expensive fabrication, limited availability of certain constituent elements, high density, and poor scope for chemical tunability. A promising design strategy for next-generation magnets relies on the versatile coordination chemistry of abundant metal ions and inexpensive organic ligands. Following this approach, we report the general, simple, and efficient synthesis of lightweight, molecule-based magnets by postsynthetic reduction of preassembled coordination networks that incorporate chromium metal ions and pyrazine building blocks. The resulting metal-organic ferrimagnets feature critical temperatures up to 242°C and a 7500-oersted room-temperature coercivity.

Аннотация: An analytical solution for the spin-wave spectrum of the two-sublattice 1D magnet with SA = SB = 1 and twisting easy planes has been obtained. Such planes are mutually twisted by an angle φ relative to each other. For the case of mutually orthogonal easy planes φ = π/2, the spectrum vs. quasi-momentum dependence has been compared with that of an easy-axis magnet with the easy axis aligned along the line of intersection of the planes. An analogy of the spectra of the models has been shown, indicating the possibility of the effective easy axis anisotropy in easy-plane two-sublattice single-chain magnets.
