Selective imaging of terahertz electric field of phonon-polariton in LiNbO
Keita Matsumoto, Takuya Satoh
Coherent phonon-polaritons have attracted a considerable amount of interest owing to their relevance to nonlinear optics and terahertz (THz)-wave emissions. Therefore, it is import…
Observation of evanescent spin waves in the magnetic dipole regime
Keita Matsumoto, Isao Yoshimine, Kosei Himeno +2
We observed spin-wave transmission through an air gap that works as a prohibited region. The spin waves were excited by circularly polarized pump pulses via the inverse Faraday eff…
Observation of terahertz magnon of Kaplan-Kittel exchange resonance in yttrium-iron garnet by Raman spectroscopy
Wei-Hung Hsu, Ka Shen, Yasuhiro Fujii +2
Backscattering Raman spectroscopic investigations were performed on an yttrium-iron garnet single crystal using linearly and circularly polarized light. A terahertz (THz) magnon of…
Ultrafast Light-driven Simultaneous Excitation of Coherent Terahertz Magnons and Phonons in Multiferroic BiFeO
Pritam Khan, Masataka Kanamaru, Keita Matsumoto +2
The ultrafast switching of magnetization in multiferroic materials by a femtosecond laser could provide various advantages in photonics and magnonics. An efficient approach to cont…
