Encoding orbital angular momentum of light in magnets
Hiroyuki Fujita, Masahiro Sato
Breaking the diffraction limit and focusing laser beams to subwavelength scale are becoming possible with the help of recent developments in plasmonics. Such subwavelength focusing…
Magnetic thermal conductivity far above the Néel temperatures in the Kitaev-magnet candidate -RuCl
Daichi Hirobe, Masahiro Sato, Yuki Shiomi +2
We have investigated the longitudinal thermal conductivity of -RuCl, the magnetic state of which is considered to be proximate to a Kitaev honeycomb model, along with the…
Observation of spin current in quantum spin liquid
Daichi Hirobe, Masahiro Sato, Takayuki Kawamata +6
Spin liquid is a state of electron spins in which quantum fluctuation breaks magnetic ordering while maintaining spin correlation. It has been a central topic in magnetism because…
Ultrafast generation of skyrmionic defects with vortex beams: printing laser profiles on magnets
Hiroyuki Fujita, Masahiro Sato
Controlling electric and magnetic properties of matter by laser beams is actively explored in the broad region of condensed matter physics, including spintronics and magneto-optics…
Laser-Driven Multiferroics and Ultrafast Spin Current Generation
Masahiro Sato, Shintaro Takayoshi, Takashi Oka
We propose an ultrafast way to generate spin chirality and spin current in a class of multiferroic magnets using a terahertz circularly polarized laser. Using the Floquet formalism…
