High-resolution spectroscopy of Pr3+ions in YAl3(BO3)4:Pr3+. Crystal-field, hyperfine,and electron-deformation interactions
B. Z. Malkin, T. A. Igolkina, K. N. Boldyrev +3
Optical transmission spectra of YAl3(BO3)4 crystals doped with the Pr3+ ions in concentrations 1 and 2.5 at. % were studied by high-resolution (up to 0.05 cm-1) Fourier spectroscop…
Incipient geometric lattice instability of cubic fluoroperovskites
R. M. Dubrovin, A. C. Garcia-Castro, N. V. Siverin +4
Inorganic metal halide perovskites are promising materials for next-generation technologies due to a plethora of unique physical properties, many of which cannot be observed in the…
Lattice dynamics and electronic transitions in a structurally-complex layered copper borate Cu(BO)
A. D. Molchanova, M. A. Prosnikov, R. M. Dubrovin +5
Copper borate Cu(BO) is a complex compound with a layered crystallographic structure in which the Jahn-Teller active and magnetic copper Cu ions occupy sixteen n…
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-…
Antiferromagnetic dichroism and Davydov splitting of 3d-excitons in a complex multisublattice magnetoelectric CuB2O4
K. N. Boldyrev, R. V. Pisarev, L. N. Bezmaternykh +1
The space and time symmetry breaking at magnetic phase transitions in multiferroics results in a number of strongly pronounced optical effects. Our high-resolution spectroscopic st…
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…
