Helical dichroism for hybridized quadrupole plasmon modes in twisted nanorods
Takahiro Uto, An'an Wu, Tsutomu Shimura +1
Helical dichroism (HD), originating from the interplay between chiral plasmonic structures and left and right vortex light carrying orbital angular momentum (OAM), has attracted si…
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…
Excitation of multiple phonon modes in copper metaborate CuBO via non-resonant impulsive stimulated Raman scattering
Kotaro Imasaka, Roman V. Pisarev, Leonard N. Bezmaternykh +3
Excitation of four coherent phonon modes of different symmetries has been realized in copper metaborate CuBO via impulsive stimulated Raman scattering (ISRS). Phonons were…
Unidirectional control of optically induced spin waves
Isao Yoshimine, Yoshito Y. Tanaka, Tsutomu Shimura +1
Unidirectional control of optically induced spin waves in a rare-earth iron garnet crystal is demonstrated. We observed the interference of two spin-wave packets with different ini…
Ultrafast optical excitation of coherent magnons in antiferromagnetic NiO
Christian Tzschaschel, Kensuke Otani, Ryugo Iida +5
In experiment and theory, we resolve the mechanism of ultrafast optical magnon excitation in antiferromagnetic NiO. We employ time-resolved optical two-color pump-probe measurement…
Two-Dimensional Propagation of a Photoinduced Spin Wave Packet
Yuki Terui, Takuya Satoh, Rai Moriya +5
We report the two-dimensional propagation of photoinduced spin wave packets in Bi-doped rare-earth iron garnet. Spin waves were excited nonthermally and impulsively by a circularly…
