Significant modulation of acoustoelectric current associated with charge density wave transitions
Natsumi Nikaido, Takuya Kawada, Koji Fujiwara +5
We studied acoustoelectric (AE) currents in materials that undergo charge density wave (CDW) transitions, induced by a surface acoustic wave (SAW) on a piezoelectric substrate. The…
Observation of Shapiro Steps in the Charge Density Wave State Induced by Strain on a Piezoelectric Substrate
Koji Fujiwara, Takuya Kawada, Natsumi Nikaido +4
Recent development in nanotechnology has enabled us to investigate the dynamic properties of van der Waals materials on a piezoelectric substrate. Here we report on the dynamics of…
Generation of a single-cycle surface acoustic wave pulse on LiNbO for application to thin film materials
Koji Fujiwara, Shunsuke Ota, Tetsuo Kodera +5
Surface acoustic wave (SAW) technology has been explored in thin-film materials to discover fundamental phenomena and to investigate their physical properties. It is used to excite…
Spin phase detection by spin current in a chiral helimagnet
Nan Jiang, Shota Suzuki, Issei Sasaki +9
Helimagnets, characterized by a helical arrangement of magnetic moments, possess unique internal degrees of freedom, including the spin phase, defined by the phase of the helical m…
