Skyrmion confinement in ultrathin film nanostructures in the presence of Dzyaloshinskii-Moriya interaction
S. Rohart, A. Thiaville
We study the modification of micromagnetic configurations in nanostructures, due to the Dzyaloshinskii-Moriya interaction (DMI) that appear at the interface of an ultrathin film. W…
NV-center imaging of bubble domains in a 6 Å film of cobalt with perpendicular magnetization
J. -P. Tetienne, T. Hingant, L. Rondin +6
We employ a scanning NV-center microscope to perform stray field imaging of bubble magnetic domains in a perpendicularly magnetized Pt/Co/AlOx trilayer with 6 Å of Co. The stray fi…
Quantitative stray field imaging of a magnetic vortex core
J. -P. Tetienne, T. Hingant, L. Rondin +4
Thin-film ferromagnetic disks present a vortex spin structure whose dynamics, added to the small size (~10 nm) of their core, earned them intensive study. Here we use a scanning ni…
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…
Stray-field imaging of magnetic vortices with a single diamond spin
L. Rondin, J. P. Tetienne, S. Rohart +5
Despite decades of advances in magnetic imaging, obtaining direct, quantitative information with nanometer scale spatial resolution remains an outstanding challenge. Recently, a ne…
