Аннотация: A comparative study was performed of the low-temperature high-resolution absorption spectra of the Yb3+ probe in R1−xYbxAl3(BO3)4 (R = Y, Tm, Lu) crystals grown by flux technique independently in four different laboratories using different solvents. We show that the incorporation of solvent components into the crystal in the course of crystallization gives rise to spectral satellites of the Yb3+ 0(2F7/2) → 0′(2F5/2) absorption lines and assign particular satellites to the Yb3+ centers near the bismuth and molybdenum impurities (which decrease the transparency of YAB in the UV spectral range). We suggest this spectroscopic method for a rapid analysis of the quality of UV laser crystals and for improvement of growth technologies.

Аннотация: Various resonance modes were observed in the transmission spectra of rare-earth iron borates RFe 3(BO 3) 4 (R = Nd 3+, Sm 3+, Gd 3+) at the frequency range 100-600 GHz, which were attributed to collective magnetic excitations in the exchange coupled Fe- and R-subsystems, i.e. antiferromagnetic (Fe) resonance and electron transitions in the R-ions. Strong interaction of the Fe and R oscillations was revealed and theoretically analyzed taking into account feature of the R-ion ground state. Intensities of the coupled modes (contributions to magnetic permeability) strongly depend on a difference of Fe and R ions g-factors that allows defining the sign of the latter. In particular, an appreciable intensity of exchange (Nd) modes in NdFe 3(BO 3) 4 is caused by g Nd?,|| < 0 whereas in GdFe 3(BO 3) 4 with gGd ? gFe ? 2 the exchange (Gd) modes were hided due to compensation of Fe and Gd contributions. In SmFe 3(BO 3) 4, despite a negligible Sm g-factor, the Sm modes were clear observed due to their excitation via coupling with the Fe-subsystem. В© (2012) Trans Tech Publications.

Аннотация: Temperature dependent neutron diffraction studies were performed on SmFe3(BO3)4. The crystallographic structure was determined to stay as R32 over the whole studied temperature range of 2 K ‹ T ‹ 300 K. A magnetic phase transition characterized by the magnetic propagation vector κ = [0 0 3/2] takes place at TN = 34 K. The magnetic structure sees an easy-plane arrangement within the trigonal basal a–b-plane of ferromagnetic layers of iron and samarium having a canting angle of about 70° relative to each other. Neighbouring layers in the c-direction are antiferromagnetically coupled; at 2 K the magnetic moment values amount to μFe = 4.2(1) μB and μSm = 0.8(2) μB. The non-Brillouin type increase of the iron magnetic moment below TN points to a strong Fe–Sm exchange and to the simultaneous appearance of long range magnetic order on both sublattices.

Аннотация: The arrangement of a polar twin structure in Czochralski grown α-SrB4O7 crystals has been investigated. The transversal twin boundaries are stretched along [ 1 0 1 ] and [ 1 0 0 ] directions. The lateral twin boundaries are parallel to ( 0 1 0 ) plane. The twin structures have an extension up to centimeter size in all directions. Supposedly, they originate from polysynthetic polar microtwins revealed to form in ( 1 0 1 ¯ ) and ( 1 ¯ 0 1 ¯ ) growth pyramids. The dimensions, planarity and thickness stability of each individual twin are favorable for organizing quasi-phase matching conditions for nonlinear optical doubling of high-aperture beams.

Аннотация: High-resolution far-infrared reflection and polarized ellipsometry, as well as Raman scattering temperature-dependent measurements are used to study spin-phonon and electron-phonon interactions in rare-earth (RE) iron borates with the R32 structure of a natural mineral huntite, namely, in RFe3(BO3)4 with R=Pr, Nd, and Sm. Pronounced peculiarities in the ω(T) dependences at the Néel temperature TN≈32 K are observed for all the compounds studied and the origin of these peculiarities is discussed. A coupling between lattice phonons and crystal-field excitations of a RE ion manifests itself by a renormalization of frequencies and intensities of coupled modes. Modeling of the spectra has revealed the value of about 15 cm−1 for the electron–phonon coupling constant in PrFe3(BO3)4.

Аннотация: The magnetoelectric and magnetic properties of substituted aluminum borates Ho1 − x Nd x Al3(BO3)4 have been studied experimentally and theoretically. A large magnetoelectric effect exceeding all known values in isostructural compounds except for HoAl3(BO3)4 has been found. The magnetoelectric polarization of Ho0.8Nd0.2Al3(BO3)4 and Ho0.5Nd0.5Al3(BO3)4 at T = 5 K in a field of 9 T is ΔP ab (B b ) ≈ −2630 and 1380 μC/m2, respectively. A theoretical consideration based on the crystal field model for the rare-earth ion made it possible to interpret all measured properties within the unified approach. The crystal field parameters have been determined. The temperature (3–300 K) and field (up to 9 T) dependences of the magnetization and the temperature (5–100 K) and field (up to 9 T) dependences of the polarization have been described. The studied properties of Ho1 − x Nd x Al3(BO3)4 have been compared with those of HoAl3(BO3)4 demonstrating record-high polarization values.

Аннотация: Resonance modes that are due to magnetic excitations in the exchange-coupled subsystems of rare-earth ions (R = Nd3+, Sm3+, and Gd3+) and Fe3+ ions have been detected in submillimeter transmission spectra (0.1-0.6 THz) of RFe3(BO3)(4) iron borate-multiferroic single crystals. The strong interaction between spin oscillations of the Fe and R subsystems has been revealed, which determines the behavior of the modes depending on the anisotropy of the exchange splitting of the ground doublet of the R ion. It has been shown that the intensities of coupled modes (contributions to the magnetic permeability) depend strongly on the difference between the g factors of Fe and R ions. This dependence makes it possible to determine the sign of the latter g factor. In particular, a noticeable intensity of exchange Nd modes in NdFe3(BO3)(4) is due to an increase in their contribution at g(perpendicular to,parallel to)(Nd) 0, while in GdFe3(BO3)(4) with g(Gd) approximate to g(Fe) approximate to 2, the Fe and Gd contributions compensate each other and the exchange (Gd) mode is not observed. In spite of the weak interaction of Sm ions with the magnetic field, SmFe3(BO3)(4) exhibits resonance modes, which are attributed to the excitation of Sm ions through the Fe subsystem.

Аннотация: Hard x-ray scattering experiments with a photon energy of 100 keV were performed as a function of temperature and applied magnetic field on selected compounds of the RFe3(BO3)4 family. The results show the presence of several diffraction features, in particular, nonresonant magnetic reflections in the magnetically ordered phase and structural reflections that violate the diffraction conditions for the low-temperature phase P3(1)21 of the rare-earth iron borates. The temperature and field dependence of the magnetic superlattice reflections corroborate the magnetic structures of the borate compounds obtained by neutron diffraction. The detailed analysis of the intensity and scattering cross section of the magnetic reflection reveals details of the magnetic structure of these materials such as the spin domain structure of NdFe3(BO3)(4) and GdFe3(BO3)(4). Furthermore we find that the correlation length of the magnetic domains is around 100 angstrom for all the compounds and that the Fe moments are rotated 53 degrees +/- 3 degrees off from the hexagonal basal plane in GdFe3(BO3)(4).

Аннотация: Neutron diffraction, susceptibility and magnetization measurements (for R = Er only) were performed on iron borates RFe3(BO3)(4) (R = Pr, Er) to investigate details of the crystallographic structure, the low temperature magnetic structures and transitions and to study the role of the rare earth anisotropy. PrFe3(BO3)(4), which crystallizes in the spacegroup R32, becomes antiferromagnetic at T-N = 32 K, with t = [0 0 3/2], while ErFe3(BO3)(4), which keeps the P3(1)21 symmetry over the whole studied temperature range 1.5 K < T < 520 K, becomes antiferromagnetic below T-N = 40 K, with tau = [0 0 1/2]. Both magnetic propagation vectors lead to a doubling of the crystallographic unit cell in the c-direction. Due to the strong polarization of the Fe-sublattice, the magnetic ordering of the rare earth sublattices appears simultaneously at T-N. The moment directions are determined by the rare earth anisotropy: easy-axis along c for PrFe3(BO3)(4) and easy-plane a-b for ErFe3(BO3)(4). There are no spin reorientations present in either of the two compounds but there is the appearance below 10 K of a minority phase in the Er-compound adopting a 120 degrees arrangement of the Er-moments.

Аннотация: SmFe3(BO3)(4) belongs to the family of rare-earth RFe3(BO3)(4) multiferroics. We present the first measurements of the optical spectra of SmFe3(BO3)(4) (on single crystals) and report the data on the crystal-field levels and their symmetries for the ground multiplet H-6(5/2) [0 (Gamma(4)). 135 (Gamma(56)), and 220 (Gamma(4)) cm(-1)] and on the ground-state exchange splitting (13.2 cm(-1) at 1.7 K), important to interpret the magnetic, magnetoelectric, and thermodynamic properties of this compound. The observed exchange splitting of the Sm3+ Kramers doublets manifests the magnetic ordering in SmFe3(BO3)(4) at 32 +/- 1 K. From a comparison of the temperature-dependent spectra of the Sm3+ ion in SmFe3(BO3)(4) and in Nd-Gd mixed iron borate where the magnetic spin reorientation has been found earlier, we suggest the easy-plane arrangement of the Fe spins in SmFe3(BO3)(4). The samarium iron borate preserves the R32 (D-3(7)) crystal structure at all the investigated temperatures (down to 1.7 K). (C) 2010 Elsevier B.V. All rights reserved.

Аннотация: Neutron diffraction, susceptibility and magnetization measurements were performed on iron borates RFe(3)(BO(3))(4)(R = Y, Ho) to investigate the low temperature magnetic structures and to clarify the role of the rare earth in the formation of the long-range magnetic order. Both compounds see an identical magnetic propagation vector tau = [ 0, 0, 1/2] within the P3(1)21 crystallographic space group appear at Neel temperatures of T(N) = 37 K for the Y and TN = 38 K for the Ho compound. The strong polarization effect of the Fe sublattice on the Ho(3+) ions leads to the simultaneous ordering of both sublattices while the competition between their anisotropies governs the spin-reorientation process at T(SR) = 5 K. The results obtained are discussed in the framework of the determined structural details and the specific rare-earth ions present including information on compounds investigated earlier.

Аннотация: Temperature-dependent high-resolution optical spectra of the Er3+ probe ion in DyFe3(BO3)(4) and HoFe3(BO3)(4) are reported. The data provide the temperature of magnetic ordering and direction of the Fe3+ magnetic moments. Both compounds order magnetically at T-N = 39 +/- 1K. The magnetic structure of DyFe3(BO3)(4) is of the easy-axis type, while that of HoFe3(BO3)(4) is of the easy-plane type. The role of anisotropic interactions between the iron and the rare-earth subsystems is discussed. (c) 2007 Elsevier B.V. All rights reserved.

Аннотация: Magnetic and optical properties of GdFe3-xGax(BO3)(4) single crystals are investigated by Mossbauer and optical spectroscopy. The GdFe3(BO3)(4) multielectron band structure model is derived. A high- and low-spin crossover of Fe3+ ion, a collapse of the magnetic moment, the suppression of Coulomb correlations, and insulator-semiconductor transition are predicted. The jump of an energy gap is measured at pressure 43 GPa. (c) 2005 Elsevier B.V. All rights reserved.
