Revealing the role of orbital magnetism in ultrafast laser-induced demagnetization in multisublattice metallic magnets by terahertz spectroscopy
T. J. Huisman, R. V. Mikhaylovskiy, A. Tsukamoto +2
Simultaneous detection of THz emission and transient magneto-optical response is employed to study ultrafast laser-induced magnetization dynamics in multisublattice magnets NdFeCo…
All-optical magnetization switching in ferrimagnetic alloys: deterministic vs thermally activated dynamics
L. Le Guyader, S. El Moussaoui, M. Buzzi +7
Using photo-emission electron microscopy with X-ray magnetic circular dichroism as a contrast mechanism, new insights into the all-optical magnetization switching (AOS) phenomenon…
Nanoscale confinement of all-optical switching in TbFeCo using plasmonic antennas
TianMin Liu, Tianhan Wang, Alexander H. Reid +17
All-optical switching (AOS) of magnetic domains by femtosecond laser pulses was first observed in the transition metal-rare earth (TM-RE) alloy GdFeCo1-5; this phenomenon demonstra…
Sub-diffraction sub-100 ps all-optical magnetic switching by passive wavefront shaping
L. Le Guyader, M. Savoini, S. El Moussaoui +7
The recently discovered magnetization reversal driven solely by a femtosecond laser pulse has been shown to be a promising way to record information at record breaking speeds. Seek…
