High-temperature terahertz optical diode effect without magnetic order in polar FeZnMoO
Shukai Yu, Bin Gao, Jae Wook Kim +5
We present a terahertz spectroscopic study of polar ferrimagnet FeZnMoO. Our main finding is a giant high-temperature optical diode effect, or nonreciprocal directional dic…
Terahertz frequency magnetoelectric effect in Ni doped CaBaCoO
Shukai Yu, C. Dhanasekhar, Venimadhav Adyam +8
We present a study of terahertz frequency magnetoelectric effect in ferrimagnetic pyroelectric CaBaCoO and its Ni-doped variants. The terahertz absorption spectrum of these…
The role of spin fluctuations in the conductivity of CrO
Kate H. Heffernan, Shukai Yu, Skylar Deckoff-Jones +3
We present a time-resolved terahertz spectroscopic study of the half-metallic ferromagnet CrO. The ultrafast conductivity dynamics excited by an optical pump displays a very sh…
Spin-dependent polaron formation dynamics in EuYMnO probed by femtosecond pump-probe spectroscopy
Diyar Talbayev, Jinho Lee, Stuart A. Trugman +5
We present a femtosecond optical pump-probe study of the multiferroic manganite EuYMnO. The optical response of the material at pump energies of 1.55 and 3.1…
Terahertz spectroscopy of spin waves in multiferroic BiFeO in high magnetic fields
U. Nagel, Randy S. Fishman, T. Katuwal +5
We have studied the magnetic field dependence of far-infrared active magnetic modes in a single ferroelectric domain \BFO/ crystal at low temperature. The modes soften close to the…
Hybridization and superconducting gaps in heavy-fermion superconductor PuCoGa5 probed via the dynamics of photoinduced quasiparticles
D. Talbayev, K. S. Burch, Elbert E. M. Chia +8
We have examined the relaxation of photoinduced quasiparticles in the heavy-fermion superconductor PuCoGa5. The deduced electron-phonon coupling constant is incompatible with the m…
