Sub-millimeter propagation of antiferromagnetic magnons via magnon-photon coupling
Ryo Kainuma, Keita Matsumoto, Toshimitsu Ito +1
For the realization of magnon-based current-free technologies, referred to as magnonics, all-optical control of magnons is an important technique for both fundamental research and…
Chiral phonons: circularly polarized Raman spectroscopy and calculations in a chiral crystal tellurium
Kyosuke Ishito, Huiling Mao, Kaya Kobayashi +5
Recently, phonons with chirality (chiral phonons) have attracted significant attention. Chiral phonons exhibit angular and pseudo-angular momenta. In circularly polarized Raman spe…
Observation of quasi-elastic light scattering in BiFeO
Eiichi Oishi, Yasuhiro Fujii, Akitoshi Koreeda +2
We observed quasi-elastic light scattering (QELS) in BiFeO using Raman spectroscopy over a temperature range of 300-860 K. The QELS has two components: a narrow and broad compo…
Truly chiral phonons in α-HgS
Kyosuke Ishito, Huiling Mao, Yusuke Kousaka +6
Chirality is a manifestation of the asymmetry inherent in nature. It has been defined as the symmetry breaking of the parity of static objects, and the definition was extended to d…
Ultrafast Optomagnonics in Ferrimagnetic Multi-Sublattice Garnets
Andrzej Stupakiewicz, Takuya Satoh
This review discusses the ultrafast magnetization dynamics within the gigahertz to terahertz frequency range in ferrimagnetic rare-earth iron garnets with different substitutions.…
Efficient spin excitation via ultrafast damping-like torques in antiferromagnets
Christian Tzschaschel, Takuya Satoh, Manfred Fiebig
Damping effects form the core of many emerging concepts for high-speed spintronic applications. Important characteristics such as device switching times and magnetic domain-wall ve…
