Influence of the low local symmetry of Er3+ ions on magnetic circular dichroism and absorption spectra of f-f transitions in ErFe3(BO3)4 single crystal / A. V. Malakhovskii, V. V. Sokolov, I. A.

Er3+ ion -- f-f transitions -- Magnetic circular dichroism -- Rare earth ferroborates
Аннотация: Linearly polarized absorption spectra and magnetic circular dichroism (MCD) spectra of ErFe3(BO3)4 single crystal were measured in the range of 9000–23000 cm−1 at 90 K. The absorption spectra of f-f transitions were decomposed into the Lorentz shape components and intensities of the components were found. MCD spectra permitted us to measure the Zeeman splitting of some transitions and so to determine changes of the Landé factor along the C3 axis of the crystal during these transitions. Optical and magneto-optical properties of f-f transitions in the ErFe3(BO3)4 crystal were compared with those in the ErAl3(BO3)4 crystal. Substantial difference of the properties connected with the difference of the Er3+ ions local symmetry in two crystals was revealed. Large splitting of one of the f-f transitions without magnetic field, which is not possible for the Kramers doublets, was observed. It was explained by appearance of two absorbing centers due to the local decrease of symmetry in the excited state. Appreciable difference of the local vibrations energy in some excited states was revealed.

Holmium and neodymium ferroborates -- Judd–Ofelt parameters
Аннотация: Polarized absorption spectra of ferroborates HoFe3(BO3)4, NdFe3(BO3)4 and Ho0.75Nd0.25Fe3(BO3)4 were measured at room temperature in spectral range 4000–24500 cm−1 (400–2500 nm). The studied single crystals were grown from solution-melts. Intensities of the f-f transitions were measured and the Judd–Ofelt parameters Ωλ of Ho3+ and Nd3+ ions in the studied crystals were calculated. It was revealed that the crystals content not strongly influences the Judd–Ofelt parameters. The Ω2 parameter for Ho3+ ion is the most sensitive to the crystal content. Linear dichroism of the hypersensitive transitions appeared to be the largest one for both rare earth ions.

Аннотация: Raman spectra of a HoFe3(BO3)4 crystal chip has been investigated at simultaneously high temperature and high pressure (up to 7.1 GPa and 560 K). On the basis of Raman analysis, the assignment to one of the two possible crystal phases has been made. The experimental p–T phase diagram of HoFe3(BO3)4 was established. An increase in the pressure leads to an increase in the temperature of transition. The phase boundary equation was obtained. Neither triple points nor a phase with new symmetry was revealed in the phase diagram. A critical point with the temperature T = 560 K and the pressure p = 2.53 GPa was found. The nanocrystals with different shapes began to grow on crystal surface after reaching that point. The composition of new nanocrystals is identical to the composition of initial crystal.

Аннотация: The magnetic, magnetoelectric, and magnetoelastic properties of DyFe3(BO3)(4) single crystals and the Nd0.75Dy0.25Fe3(BO3)(4) substituted compound with the competitive Nd-Fe and Dy-Fe exchange interactions have been investigated in magnetic fields up to 210 kOe. It has been shown that the antiferromagnetic state in Nd0.75Dy0.25Fe3(BO3)(4) below the N,el temperature is easy-plane and a spontaneous spin-reorientation transition to a uniaxial state occurs near 25 K. Anomalies are observed in various physical characteristics in a spin-flop transition induced by the magnetic field along the trigonal axis. The H-T phase diagrams are constructed; they are in good agreement with a simple model taking into account the anisotropy of the exchange splitting and g factors of the ground doublets of the Dy3+ and Nd3+ ions. The features of the magnetoelectric effect in various magnetic phases have been studied. Spontaneous electric polarization has been revealed in the region of the existence of an easy-plane antiferromagnetic state in the substituted compound. A qualitative theoretical justification of the possibility of the appearance of the spontaneous spin-reorientation transition in the Nd0.75Dy0.25Fe3(BO3)(4) substituted compound is given.

The anomalies corresponding to the phase transition of the second order have been detected at the temperatures of magnetic phase transitions, being consistent with previously reported results of the magnetization study. A number of anomalies in the temperature dependences of the spectral lines associated with the occurrence of magnetic order. A mode corresponding to two-magnon scattering was revealed. Comparison of the features of low-temperature low-frequency spectra of solid solutions Ho-Nd and Sm-La has been carried out.

Аннотация: Sm1-xLaxFe3(BO3)4 (x = 0, 0.75) single crystals were synthesized using the flux method. The crystal nucleation procedure and flux parameters are reported. Conditions for growing the Sm1-xLaxFe3(BO3)4 (x = 0, 0.75) single crystals are described. The prepared crystals were studied by Raman spectroscopy in the temperature range of T = 10-300 K. The spectral region corresponding to temperatures of T = 10-55 K, which involves the temperatures of the magnetic phase transition TN = 32 K for x = 0 and TN = 31 K for x = 0.75, was thoroughly analyzed. Anomalies related to the magnetic ordering established in both compounds were found. The main changes occur in the low-wavenumber region (up to 100 cm-1), where the mode corresponding to magnon scattering arises. This mode is shown to have the internal structure indicative of the occurrence of unstable vibrations (40-80 cm-1). The results obtained are analyzed by calculating the empirical lattice dynamics in Sm1-xLaxFe3(BO3)4 with x = 0 and x = 1. © 2016 American Chemical Society.

magnetic phase transitions -- rare-earth ferroborates RFe3(BO3)4 -- antiferromagnetic resonance
Аннотация: The magnetic structure of the mixed rare-earth system PrxY1-xFe3(BO3)4 (x = 0.75, 0.67, 0.55, 0.45, 0.25) was studied via magnetic and resonance measurements. These data evidence the successive spin reorientation from the easy-axis antiferromagnetic structure formed in PrFe3(BO3)4 to the easy-plane one of YFe3(BO3)4 associated with the weakening of the magnetic anisotropy of the Pr subsystem due to its diamagnetic dilution by nonmagnetic Y. This reorientation occurs through the formation of an inclined magnetic structure, as was confirmed by our previous neutron research in the range of x = 0.67 ? 0.45. In the compounds with x = 0.75 and 0.67 whose magnetic structure is close to the easy-axis one, a two-step spin reorientation takes place in the magnetic field H||c. Such a peculiarity is explained by the formation of an interjacent inclined magnetic structure with magnetic moments of Fe ions located closer to the basal plane than in the initial state, with these intermediate states remaining stable in some ranges of the magnetic field. An approach based on a crystal field model for the Pr3+ ion and the molecular-field approximation is used to describe the magnetic characteristics of the system PrxY1-xFe3(BO3)4. With the parameters of the d-d and f-d exchange interactions, of the magnetic anisotropy of the iron subsystem and of the crystal field parameters of praseodymium thus determined, it is possible to achieve a good agreement between the experimental and calculated temperature and field dependences of the magnetization curves (up to 90 kOe) and magnetic susceptibilities (2-300 K). © 2016 IOP Publishing Ltd.

Аннотация: GdFe3(BO3)4, single crystals were grown from melt-solutions based on bismuth trimolybdate and lithium tungstate. Single crystals of gadolinium ferroborate from lithium-tungstate solution-melt were grown for the first time. The magnetic properties of the grown crystals are compared. It is shown that the GdFe3(BO3)4, ferroborate obtained using bismuth solution-melt trimolybdate contains impurities of Bi3+ ions (6% at.), which replace Gd3+ ions. Whereas GdFe3(BO3)4, ferroborate grown from a solution-melt based on lithium tungstate does not seem to contain such uncontrolled impurities.

Кл.слова (ненормированные):
Raman spectroscopy -- temperature dependence -- soft modes -- ferroborates -- phase diagramm
Аннотация: The Raman spectra of four crystals of TbFe3–xGax(BO3)4 solid solutions (x from 0 to 0.54) were studied in the temperature range from 8 to 350 K. The temperatures of structural phase transitions were determined. The observed spectral behavior is characteristic to condensation and restoration of soft modes. Soft modes are associated with a structural phase transition from the R32 phase to the P3121 phase. The Compositions-Temperature phase diagram was constructed.
