Observation of Orbit-Orbit Torques: Highly Efficient Torques on Orbital Moments Induced by Orbital Currents
This study demonstrates that orbital currents generated by the orbital Hall effect in chromium can be efficiently injected into terbium to induce a highly effective orbit-orbit torque (OOT) with a dampinglike efficiency of ~3.66, offering a promising pathway for manipulating orbital magnetization in orbitronics.
