Single laser pulse induced magnetization switching in in-plane magnetized GdCo alloys
Jun-Xiao Lin, Michel Hehn, Thomas Hauet +8
The discovery of all-optical ultra-fast deterministic magnetization switching has opened up new possibilities for manipulating magnetization in devices using femtosecond laser puls…
Ultrafast single-pulse all-optical switching in synthetic ferrimagnetic Tb/Co/Gd multilayers

In this work, we investigate single-shot all-optical switching (AOS) in Tb/Co/Gd/Co/Tb multilayers in an attempt to establish AOS in synthetic ferrimagnets with high perpendicular…
Bringing ultimate depth to scanning tunnelling microscopy: deep subsurface vision of buried nano-objects in metals
Oleg Kurnosikov, Muriel Sicot, Emilie Gaudry +3
A method for subsurface visualization and characterization of hidden subsurface nano-structures based on Scanning Tuneling Microscopy/Spectroscopy (STM/STS) has been developed. The…
Current-induced spin torques on single GdFeCo magnetic layers
David Céspedes-Berrocal, Heloïse Damas, Sébastien Petit-Watelot +16
Spintronics exploits spin-orbit coupling (SOC) to generate spin currents, spin torques, and, in the absence of inversion symmetry, Rashba, and Dzyaloshinskii-Moriya interactions (D…
Domain-wall motion induced by spin transfer torque delivered by helicity-dependent femtosecond laser
Boyu Zhang, Yong Xu, Weisheng Zhao +8
In magnetic wires with perpendicular anisotropy, moving domain with only current or only circularly polarized light requires a high power. Here, we propose to reduce it by using bo…
Energy-efficient domain wall motion governed by the interplay of helicity-dependent optical effect and spin-orbit torque
Boyu Zhang, Yong Xu, Weisheng Zhao +6
Spin-orbit torque provides a powerful means of manipulating domain walls along magnetic wires. However, the current density required for domain wall motion is still too high to rea…
Electrical initialization of electron and nuclear spins in a single quantum dot at zero magnetic field
F. Cadiz, A. Djeffal, D. Lagarde +18
The emission of circularly polarized light from a single quantum dot relies on the injection of carriers with well-defined spin polarization. Here we demonstrate single dot electro…
Current-induced Pinwheel Oscillations in Perpendicular Magnetic Anisotropy Spin Valve Nanopillars
Richard Choi, J. A. Katine, Stephane Mangin +1
Nanopillar spin valve devices are typically comprised of two ferromagnetic layers: a reference layer and a free layer whose magnetic orientation can be changed by both an external…
