Spectroscopy of f-f transitions, crystal-field calculations, and magnetic and quadrupole helix chirality in DyFe(BO)
M. N. Popova, E. P. Chukalina, K. N. Boldyrev +3
Recently, quadrupole helix chirality and its domain structure was observed in resonant x-ray diffraction experiments on DyFe(BO) using circularly polarized x rays [T. U…
Bifurcations observed in the spectra of coupled electron-phonon modes in multiferroic subjected to a magnetic field
K. N. Boldyrev, T. N. Stanislavchuk, A. A. Sirenko +3
We report on bifurcations effect mediated by the electron-phonon coupling in a concentrated rare-earth-containing antiferromagnet, observed in the spectra of coupled -electron-…
Novel Layered Iridate Ba7Ir3O13+δ Thin Films with Colossal Permittivity
Ludi Miao, Yan Xin, Jinyu Liu +7
Ba7Ir3O13+δ in thin film form is discovered. These films are characterized by colossal permittivity (CP) ~104 at room temperature, attributable to the colossal internal barrier lay…
A broadband silicon quarter-wave retarder for far-infrared spectroscopic circular dichroism
Xiaoxiang Xi, R. J. Smith, T. N. Stanislavchuk +4
The high brightness, broad spectral coverage and pulsed characteristics of infrared synchrotron radiation enable time-resolved spectroscopy under throughput-limited optical systems…
Splitting of a nondegenerate phonon mode in PrFe3(BO3)4: 4f crystal-field level between TO and LO phonon frequencies
K. N. Boldyrev, T. N. Stanislavchuk, A. A. Sirenko +2
A new effect originating from the crystal-field-excitation - phonon coupling was observed (in the far infrared spectra of a multiferroic PrFe3(BO3)4). The reststrahlen band corresp…
Magnons and crystal field transitions in hexagonal REMnO3 (RE = Er, Tm, Yb, Lu) single crystals
E. C. Standard, T. Stanislavchuk, A. A. Sirenko +2
Far-infrared optical transmission spectra of the antiferromagnetic resonances, or magnons, and crystal field transitions have been studied in hexagonal REMnO3 (RE = Er, Tm, Yb, Lu)…
