A crystal-field route to THz-driven magnetization
T. Zalewski, M. S. Mrudul, Y. Lee +5
Light carries angular momentum, but the microscopic pathways that transform it into magnetization remain elusive. Here we establish that crystal-field excitations, historically vie…
Optical switching of antiferromagnetic domains by nonreciprocal heat current
Takeshi Hayashida, Shunsuke Izumikawa, Kenta Kimura +2
What distinguishes front from back? In physics, such directionality emerges only when an underlying symmetry is broken. Antiferromagnets that inherently break both space-inversion…
Photoinduced strain and polarization switching in barium titanate in the far-infrared spectral range
Maarten Kwaaitaal, Daniel Lourens, Carl S. Davies +1
Short mid-infrared laser pulses efficiently facilitate ultrafast manipulation of ferroic order parameters, including full reversal of magnetization or ferroelectric polarization, w…
Photo-induced switching of magnetisation in the epsilon-near-zero regime
Héloïse Damas, Carl S. Davies, Petr M. Vetoshko +3
The possibility of controlling spins using ultrashort light and strain pulses has triggered intense discussions about the mechanisms responsible for magnetic re-ordering. All-optic…
