Imaging non-collinear antiferromagnetic textures via single spin relaxometry
Aurore Finco, Angela Haykal, Rana Tanos +13
Antiferromagnetic materials are promising platforms for next-generation spintronics owing to their fast dynamics and high robustness against parasitic magnetic fields. However, nan…
Electrical spectroscopy of forward volume spin waves in perpendicularly magnetized materials
M. Sushruth, M. Grassi, K. Ait-Oukaci +8
We study the potential of all-electrical inductive techniques for the spectroscopy of propagating forward volume spin waves. We develop a one-dimensional model to account for the e…
Chaos in Magnetic Nanocontact Vortex Oscillators
Thibaut Devolder, Damien Rontani, Sébastien Petit-Watelot +10
We present an experimental study of spin-torque driven vortex self-oscillations in magnetic nanocontacts. We find that above a certain threshold in applied currents, the vortex gyr…
Nonreciprocal flexural dynamics of Dzyaloshinskii domain walls
Rémy Soucaille, Felipe Garcia-Sanchez, Joo-Von Kim +2
We revisit the description of ferromagnetic domain wall dynamics through an extended one-dimensional model by allowing flexural distortions of the wall during its motion. This is t…
Direct measurement of interfacial Dzyaloshinskii-Moriya interaction in X/CoFeB/MgO heterostructures with a scanning-NV magnetometer
I. Gross, L. J. Martínez, J. -P. Tetienne +11
The Dzyaloshinskii-Moriya Interaction (DMI) has recently attracted considerable interest owing to its fundamental role in the stabilization of chiral spin textures in ultrathin fer…
The nature of domain walls in ultrathin ferromagnets revealed by scanning nanomagnetometry
J. -P. Tetienne, T. Hingant, L. J. Martinez +13
The recent observation of current-induced domain wall (DW) motion with large velocity in ultrathin magnetic wires has opened new opportunities for spintronic devices. However, ther…
Measurement of magnetization using domain compressibility in CoFeB films with perpendicular anisotropy
N. Vernier, J. P. Adam, S. Eimer +5
We present a method to map the saturation magnetization of soft ultrathin films with perpendicular anisotropy, and we illustrate it to assess the compositional dependence of the ma…
Modified current induced domain wall motion in GaMnAs nanowire
Nicolas Vernier, Jean-Paul Adam, Andre Thiaville +4
We report on current induced domain wall propagation in a patterned GaMnAs microwire with perpendicular magnetization. An unexpected slowing down of the propagation velocity has be…
Thermally driven spin injection from a ferromagnet into a non-magnetic metal
Abraham Slachter, Frank Lennart Bakker, Jean-Paul Adam +1
Creating, manipulating and detecting spin polarized carriers are the key elements of spin based electronics. Most practical devices use a perpendicular geometry in which the spin c…
Interplay of Peltier and Seebeck effects in nanoscale nonlocal spin valves
F. L. Bakker, A. Slachter, J. -P. Adam +1
We have experimentally studied the role of thermoelectric effects in nanoscale nonlocal spin valve devices. A finite element thermoelectric model is developed to calculate the gene…
