Unveiling Orbital-mediated Ultrafast Demagnetization in Rare Earth-Transition-Metal Ferrimagnets
Jianwen Gao, Linlin Zhang, Mingli Ge +12
The ultimate speed limit of magnetic recording and spintronic devices is set by the efficiency of angular-momentum transfer during ultrafast demagnetization, yet its microscopic pa…

Orbital-Selective Engineering of Strain-Tunable Chern Insulators in Momentum Space
Jin Gao, Rongrong Chen, Lei Yang +6
Unlike conventional approaches where topological order is statically fixed post-synthesis, we demonstrate that a single external knob-strain-can independently modulate topological…
