Terahertz radiation by ultrafast spontaneous polarization modulation in multiferroic BiFeO thin films
Kouhei Takahashi, Noriaki Kida, Masayoshi Tonouchi
Terahertz (THz) radiation has been observed from multiferroic BiFeO thin films via ultrafast modulation of spontaneous polarization upon carrier excitation with illumination of…

Spectroscopic evidence for a charge-density-wave condensate in a charge-ordered manganite: Observation of collective excitation mode in PrCaMnO by using THz time-domain spectroscopy
Noriaki Kida, Masayoshi Tonouchi
THz time-domain spectroscopy was used to directly probe the low-energy (0.5--5 meV) electrodynamics of the charge-ordered manganite PrCaMnO. We revealed the exi…

Terahertz radiation from magnetoresistive PrCaMnO thin films
N. Kida, M. Tonouchi
Terahertz (THz) radiation with its spectrum extending up to 1 THz has been observed by an illumination of femtosecond optical pulses to optical switching devices fabricated on magn…
