Аннотация: We report on the emergence of new lines in the optical spectrum of the PrFe3(BO3)(4) single crystal at the magnetic ordering temperature. The transitions between singlet crystal-field sublevels of Pr3+ ion with the same transformational properties, strictly forbidden for the trigonal D-3 point symmetry of this ion in PrFe3(BO3)(4), appear below the Neel temperature and grow in intensity as a square of the order parameter. We show that the phenomenon originates from the mixing of wave functions of different Pr3+ sublevels by the Pr-Fe exchange interaction.

Аннотация: MnGeO3 single-crystal samples have been synthesized by optical zonal melting and spontaneous crystallization. X-ray crystal analysis showed the first sample to be a two-phase one with phase ratio as follows: 17% - monoclinic C2/c, and 83% - orthorhombic Pbca; the phase ratio of the second sample was unknown. Raman spectra have been produced for these samples. Lattice dynamics has been simulated and polarization dependencies of lines' intensities have been analyzed to interpret experimental Raman spectra and to attribute lines to the spectra of monoclinic and orthorhombic phases.

Low-temperature magnetic phase diagram of HoFe3(BO3)(4) holmium ferroborate: a magnetic and heat capacity study / A. . Pankrats [et al.] // J. Phys.: Condens. Matter. - 2009. - Vol. 21, Is. 43. - Ст. 436001, DOI 10.1088/0953-8984/21/43/436001. - Cited References: 20 . - ISSN 0953-8984

Аннотация: We present the results of the magnetic and heat capacity study of a magnetic phase diagram of a HoFe3(BO3)(4) single crystal. Two magnetic phase transitions are found in the low-temperature region. The transition from the paramagnetic to easy-plane antiferromagnetic state occurs at T-N = 37.4 K and is independent of an applied magnetic field. The sharp heat capacity peaks and magnetization jumps corresponding to the spontaneous and field-induced spin-reorientation transitions between the easy-axis and easy-plane states are observed below 4.7 K. Also, the additional heat capacity peaks, which can be attributed to the Schottky anomalies with the field-dependent characteristic temperatures, are found. According to the magnetic and thermal measurement data, the magnetic phase diagrams of HoFe3(BO3)(4) for the magnetic field parallel and perpendicular to the crystal axis are constructed.

Antiferromagnetic resonance in Bi2CuO4 / L. E. Svistov [et al.] // J. Exp. Theor. Phys. - 1998. - Vol. 86, Is. 6. - P. 1228-1233, DOI 10.1134/1.558595. - Cited References: 14 . - ISSN 1063-7761

Аннотация: Magnetic resonance of the low-frequency spin-wave branch in the Bi2CuO4 antiferromagnet with an easy-plane anisotropy has been studied. Angular, frequency, and temperature dependences of the position and width of the antiferromagnetic resonance (AFMR) line have been measured. Our measurements combined with earlier data [H. Ochta, K. Yoshida, T. Matsuya, T. Nanba, M. Motokawa, K. Yamada, Y. Endon, and S. Hosoya, J. Phys. Sec. Jpn. 61, 2921 (1992); E. W. Ong, G. H. Kwei, R. A. Robinson, B. L. Ramakrishna, and R. B. von Dreele, Phys. Rev. B 42, 4255 (1990)] have allowed us to determine anisotropy constants of this material and to account for the unusual character of its static susceptibility anisotropy. The AFMR line shifts to the high-field side and broadens in a temperature range of 10-15 K, and the cause of this has remained unclear. In the low-temperature range the line shows a hysteresis corresponding to a static field magnitude several times as large as the spin-flop field. The position and width of the AFMR line depend sensitively on the sample preparation technique. (C) 1998 American Institute of Physics.

Аннотация: The resonance absorption in Bi2CuO4 single crystals was found in the frequency range 35-80 GHz for H(perpendicular-to)C4 Case and it was absent for H(parallel-to)C4 case. The frequency-field dependence for H(perpendicular-to)C4 case at 4.2 K is typical for easy-plane antiferromagnets with weak magnetic anisotropy in this plane. In contrast to the sublattice magnetization of Bi2CuO4 the resonance parameters depend strongly on the temperature below 20 K. Besides, the resonance field has a considerable jump at TN which ls not typical for second order phase transitions.

Аннотация: The formation of the atomically ordered L10-FePd structure during the solid-state reaction in Fe/Pd bilayer thin films is in situ investigated by electron microscopy and electron diffraction analysis. The initial iron and palladium layers were mainly coherently oriented crystallites with the orientation relationship α-Fe (001)[110] || Pd(001)[100]. It is established that the solid-state reaction between the iron and palladium layers upon heating at a rate of 4–8°C/min starts with the formation of the FePd solid solution at 390°C; at 430°C, the formation of the atomically ordered L10-FePd structure is observed. It is shown that at the low heating rate (4–8°C/min), the L10-FePd structure with the [001] orientation relative to the film plane forms, while at the high heating rate (50°C/min) it forms with the [100], [010], and [001] orientations.

Аннотация: Crystallization of heterovalent double (Mn,Ni)3BO5 and triple (Mn,Ni,Cu)3BO5 oxyborates with the ludwigite structure is studied in fluxes based on Bi2Mo3O12 diluted with Na2CO3 or Li2CO3 carbonates. Single crystals of five (Mn,Ni)3BO5 and three (Mn,Ni,Cu)3BO5 compounds with different cation ratios are obtained. The ion concentration is determined from the analysis of the lattice parameters by powder and single crystal XRD. The comparative analysis of the polarized Raman spectra of double and triple ludwigites is presented. The actual high nickel and small copper concentrations in the crystals are discussed. The hierarchy of chemical bonds in the fluxes used in addition to the approach involving stabilization of the manganese valence state using solvent components is estimated.

Аннотация: We considered the effect of optical pumping at the f−f transitions frequency on d−f superexchange in the rare-earth antiferromagnetic ferroborate Nd0.5Gd0.5Fe3(BO3)4 between Nd3+ ions in the excited states of the 4G5/2, 2G7/2, and Fe3+ in the ground state 6A1. In the ferroborate, d−f superexchange is directly related to the strong magnetoelectric coupling observed in the ground state of the material. We show that under optical pumping at the frequency of f−f transitions 4I9/2↔(4G5/2+2G7/2) in the Nd3+ ion, the nature of the d−f interaction changes to FM. The phenomena can be explained by the occupation of the excited Nd3+ “spin pure” states with spin 1/2, or their mixing to the optically excited states with spin 3/2 due to the spin-orbit interaction. Near optically excited ions Nd3+, magnetic frustrations change from FM ordering under the d−f AFM interaction to AFM ordering under the FM interaction in the basal hexagonal plane.

Аннотация: The polarizing spectroscopy techniques in visible range optics have been used since the beginning of the 20th century to study the anisotropy of crystals based on birefringence and optical activity phenomena. On the other hand, the phenomenon of X-ray optical activity has been demonstrated only relatively recently. It is a selective probe for the element-specific properties of individual atoms in non-centrosymmetric materials. We report the X-ray Natural Circular Dichroism (XNCD) imaging technique which enables spatially resolved mapping of X-ray optical activity in non-centrosymmetric materials. As an example, we present the results of combining micro-focusing X-ray optics with circularly polarized hard X-rays to make a map of enantiomorphous twinning in a multiferroic SmFe3(BO3)4 crystal. Our results demonstrate the utility and potential of polarization-contrast imaging with XNCD as a sensitive technique for multiferroic crystals where the local enantiomorphous properties are especially important. In perspective, this brings a novel high-performance method for the characterization of structural changes associated with phase transitions and identification of the size and spatial distribution of twin domains.

Аннотация: The phonon dispersion in terbium iron borate TbFe3(BO3)4 has been measured by inelastic neutron scattering in a temperature range 180˂T˂350 K through the displacive structural transition at TS=192.5K and studied by ab initio calculations. Significant, but not complete, softening of the transverse acoustic (TA) branch has been observed at the corner of the Brillouin zone (Λ point) at temperatures T⪆TS, in full agreement with theoretical calculations. The TA soft mode undergoes considerable broadening at the Λ point near the transition temperature that can be attributed to the anharmonic interference between transverse acoustic and optical modes.
