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…
Universal scaling for the spin-electricity conversion on surface states of topological insulators
K. T. Yamamoto, Y. Shiomi, Kouji Segawa +2
We have investigated spin-electricity conversion on surface states of bulk-insulating topological insulator (TI) materials using a spin pumping technique. The sample structure is N…
