Aging and passivation of magnetic properties in Co/Gd bilayers
T. J. Kools, Y. L. W. van Hees, K. Poissonnier +5
Synthetic ferrimagnets based on Co and Gd bear promise for directly bridging the gap between volatile information in the photonic domain and non-volatile information in the magneti…
Strain effects on magnetic compensation and spin reorientation transition of Co/Gd synthetic ferrimagnets
Giovanni Masciocchi, Thomas J. Kools, Pingzhi Li +5
Synthetic ferrimagnets are an attractive materials class for spintronics as they provide access to all-optical switching of magnetization and, at the same time, allow for ultrafast…
Laser induced ultrafast Gd 4f spin dynamics in Co100-xGdx alloys by means of time-resolved XMCD
T. Ferté, M. Beens, G. Malinowski +8
We have studied the laser induced ultrafast quenching of Gd 4f magnetic order in ferrimagnetic Co100-xGdx alloys to highlight the role of the inter-atomic exchange coupling. We hav…
State-resolved ultrafast charge and spin dynamics in [Co/Pd] multilayers
Loïc Le Guyader, Daniel J. Higley, Matteo Pancaldi +17
We use transient absorption spectroscopy with circularly polarized x-rays to detect laser-excited hole states below the Fermi level and compare their dynamics with that of unoccupi…
Electrical switching of antiferromagnetic CoO | Pt across the Néel temperature
M. J. Grzybowski, C. F. Schippers, M. E. Bal +5
One of the most important challenges in antiferromagnetic spintronics is the read-out of the Néel vector state. High current densities up to 10 Acm used in the electrica…
Antiferromagnetic Hysteresis above the Spin Flop Field
M. J. Grzybowski, C. F. Schippers, O. Gomonay +11
Magnetocrystalline anisotropy is essential in the physics of antiferromagnets and commonly treated as a constant, not depending on an external magnetic field. However, we demonstra…
