Magnetically-Driven Ferroelectric Atomic Displacements in perovskite like YMnO3
D. Okuyama, S. Ishiwata, Y. Takahashi +9
Magnetically-driven ferroelectric atomic displacements of the order of 10_3$ by a single-crystal synchrotr…
Electromagnons in the spin collinear state of a triangular lattice antiferromagnet
S. Seki, N. Kida, S. Kumakura +2
Terahertz time-domain spectroscopy was performed to directly probe the low-energy (1-5 meV) electrodynamics of triangular lattice antiferromagnets CuFe1-xGaxO2 (x = 0.00, 0.01, and…
Optical Hall Effect in the Integer Quantum Hall Regime
Yohei Ikebe, Takahiro Morimoto, Ryuichi Masutomi +3
Optical Hall conductivity is measured from the Faraday rotation for a GaAs/AlGaAs heterojunction quantum Hall system in the terahertz frequency regime. The Faraday rota…
Electromagnons in the multiferroic state of perovskite manganites with symmetric-exchange striction
Y. Takahashi, S. Ishiwata, S. Miyahara +5
We have investigated electrically-active magnetic excitations (electromagnons) in perovskite manganites with the -type (up-up-down-down) spin structure by terahertz spectroscopy…
Terahertz time-domain spectroscopy of electromagnons in multiferroic perovskite manganites
N. Kida, Y. Takahashi, J. S. Lee +7
Recent spectroscopic studies at terahertz frequencies for a variety of multiferroics endowed with both ferroelectric and magnetic orders have revealed the possible emergence of a n…
