Terahertz lattice and charge dynamics in ferroelectric semiconductor SnPbTe
Y. Okamura, H. Handa, R. Yoshimi +5
The symmetry breaking induced by the ferroelectric transition often triggers the emergence of topological electronic states such as Weyl fermions in ferroelectric-like metals/semim…
Microwave directional dichroism resonant with spin excitations in the polar ferromagnet GaVS
Y. Okamura, S. Seki, S. Bordács +4
We have investigated the directional dichroism of magnetic resonance spectra in the polar ferromagnet GaVS. While four types of structural domains are energetically degener…
Element-specific soft X-ray spectroscopy, scattering and imaging studies of skyrmion-hosting compound CoZnMn
V. Ukleev, Y. Yamasaki, D. Morikawa +10
A room-temperature skyrmion-hosting compound CoZnMn has been examined by means of soft X-ray absorption spectroscopy, resonant small-angle scattering and extended refer…
Propagating spin excitations along skyrmion strings
S. Seki, M. Garst, J. Waizner +6
Magnetic skyrmions, topological solitons characterized by a two-dimensional swirling spin texture, have recently attracted attention as stable particle-like objects. In a three-dim…
Current-induced viscoelastic topological unwinding of metastable skyrmion strings
F. Kagawa, H. Oike, W. Koshibae +5
In the MnSi bulk chiral magnet, magnetic skyrmion strings of 17 nm in diameter appear in the form of a lattice, penetrating the sample thickness, 10-1,000 um. Although such a bundl…
