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…
Evidence for spin swapping from modulation of transverse resistance in magnetic heterostructures with Rashba interface
Heeman Kim, Shutaro Karube, Juan Borge +3
We investigate the transverse response under the out-of-plane magnetic field for magnetic heterostructures with Cu/Bi2O3 or Ag/Bi2O3 Rashba interfaces. We detect opposite contribut…
