Orbital torque: Torque generation by orbital current injection [PDF]
Physical Review Research, 2020 We propose a mechanism of torque generation by injection of an orbital current, which we call $\textit{orbital torque}$. In a magnetic bilayer consisting of a nonmagnet (NM) and a ferromagnet (FM), we consider a situation where the spin-orbit coupling (SOC) is present only in the FM.

Efficient conversion of orbital Hall current to spin current for spin-orbit torque switching [PDF]
Communications Physics, 2021 Spin Hall effect, an electric generation of spin current, allows for efficient control of magnetization. Recent theory revealed that orbital Hall effect creates orbital current, which can be much larger than spin-Hall-induced spin current.
