“…The investigation of weak non-resonant magnetic reflections in SmFeAsO shows that very weak signals can be measured reliably 35 . Full polarization analysis, performed at the Ho L 3 -edge of HoFe 3 (BO 3 ) 4 could be used to show the spiral magnetic order along the c-axis 36 . From azimuthal scans at the Ir L 3 -edge of Sr 2 IrO 4 , the ordering of the Ir moments in the basal plane could be determined and be related to the ordering in Ba 2 IrO 4 37 .…”

The resonant scattering and diffraction beamline P09 at PETRA III is designed for X-ray experiments requiring small beams, energy tunability, variable polarization and high photon flux. It is highly flexible in terms of beam size and offers full higher harmonic suppression. A state-of-the-art double phase-retarder set-up provides variable linear or circular polarization. A high-precision Psi-diffractometer and a heavy-load diffractometer in horizontal Psi-geometry allow the accommodation of a wide variety of sample environments. A 14 T cryo-magnet is available for scattering experiments in magnetic fields.

“…Подходящими R-ионами для синтеза и исследования замещенного ферробората с конкурирующими обменными взаимодействиями являются ионы Ho 3+ и Nd 3+ . Магнитные моменты железа в HoFe 3 (BO 3 ) 4 антиферромагнитно упорядочиваются при T N ≈ 38−39 K и при понижении до температуры T SR ≈ 4.7−5 K лежат в базисной плоскости ab, также как и магнитные моменты ионов Ho 3+ [3,8,9]. При T SR ≈ 4.7−5 K происходит спонтанный спин-переориентационный переход, в результате которого магнитные моменты Hoи Fe-подсистем становятся ориентированными вдоль оси c. В NdFe 3 (BO 3 ) 4 при T < T N ≈ 31 K все магнитные моменты лежат в базисной плоскости ab [10,4].…”

The magnetic and magnetodielectric properties of Ho_0.5Nd_0.5Fe_3(BO_3)_4 ferroborate with the competing Ho–Fe and Nd–Fe exchange couplings have been experimentally and theoretically investigated. Step anomalies in the magnetization curves at the spin-reorientation transition induced by the magnetic field B ║ c have been found. The spontaneous spin-reorientation transition temperature T _SR ≈ 8 K has been refined. The measured magnetic properties and observed features are interpreted using a single theoretical approach based on the molecular field approximation and calculations within the crystal field model of the rare-earth ion. Interpretation of the experimental data includes determination of the crystal field parameters for Ho^3+ and Nd^3+ ions in Ho_0.5Nd_0.5Fe_3(BO_3)_4 and parameters of the Ho–Fe and Nd–Fe exchange couplings.

“…In addition, there are literature reports of x-ray measurements of holmium ferroborate. 12 The authors found the occurrence of an incommensurate magnetic structure below T ¼ 22.5 K, which is below the temperature of magnetic ordering, 38 K. This structure disappears at a temperature of 4.8 K when a spin-reorientation transition occurs into the "easy-axis" phase.…”

A presentation of experimental study results obtained by antiferromagnetic resonance (AFMR) of the high-frequency properties of the multiferroic Nd 0.75 Ho 0.25 Fe 3 (BO 3 ) 4 in a broad range of temperatures and frequencies. We studied the effect of substituting the Nd 3þ ions with Ho 3þ , on the resonance properties of the Nd 0.75 Ho 0.25 Fe 3 (BO 3 ) 4 solid solution. In addition, we investigated the particularities of magnetic-field induced spin-reorientation phase transitions for Hjjc and Hjja directions, in which the anisotropy of the magnetic system is measured from "easy-axis" anisotropy to "easy-plane." The AFMR modes of a Fe 3þ subsystem are revealed. New information about the most important characteristics of AFM is obtained, including: frequency-field dependence of the AFMR spectrum, gaps in the spin-wave spectrum, effective magnetic anisotropy values, and fields of spin-reorientation transitions. It is shown that "easy-plane" anisotropy prevails in this magnet, with a weak anisotropy in the basal plane. For the first time there are observed features in the AFMR spectra that could be tied to the presence of a spatially modulated spin structure (incommensurate phase) in AFM Nd 0.75 Ho 0.25 Fe 3 (BO 3 ) 4 .
