Boris Gorshunov,Alexander G. Volkov,Igor E. Spektor,A. S. Prokhorov,A. A. Mukhin,Martin Dressel,S. Uchida,Alois Loidl +7 more
TL;DR: In this article, the backward-wave oscillators (BWOs) were used for terahertz-sub-Terahertz (THz-subTHz) spectrometers, based on continuously frequency-tunable coherent sources of radiation.
Journal ArticleDOI

TL;DR: The present study places separate H2O molecules in the structural channels of a beryl single crystal so that they are located far enough to prevent hydrogen bonding, but close enough to keep the dipole–dipole interaction, resulting in incipient ferroelectricity in the water molecular subsystem.
Journal ArticleDOI
Lattice anharmonicity and polar soft mode in ferrimagnetic M-type hexaferrite BaFe12O19 single crystal
A. S. Mikheykin,Elena S. Zhukova,Elena S. Zhukova,Elena S. Zhukova,Viktor I. Torgashev,Anna G. Razumnaya,Yury I. Yuzyuk,Boris Gorshunov,Boris Gorshunov,Boris Gorshunov,A. S. Prokhorov,A. S. Prokhorov,Aleksandr E. Sashin,Aleksandr E. Sashin,A. A. Bush,Martin Dressel +15 more
TL;DR: In this article, the polar phonon modes in BaFe12O19 single crystal were studied in the temperature range from 6 to 300 K by polarized infrared spectroscopy, and it was shown that the phonon spectrum of the crystal is strongly anharmonic and unstable with respect to long-wavelength fluctuations of the dielectric permittivity along the hexagonal axis.
Journal ArticleDOI
Phase transitions in Sm1–xSrxMnO3 single crystals (0 ≤ x ≤ 0.8)
TL;DR: In this article, the T-x phase diagram has been revised and the compensation points of spontaneous weak ferromagnetic moment have been observed for pure SmMnO 3 and for low doped compositions (0 ≤ x ≤ 0.05).
Journal ArticleDOI

TL;DR: In this article, single-domain Sr1−x/12Cax/12Fe12−xAlxO19 particles are synthesized by a simple citrate auto-combustion method.
