Electrical detection and nucleation of a magnetic skyrmion in a magnetic tunnel junction observed via operando magnetic microscopy
by J. Urrestarazu Larrañaga, Naveen Sisodia, Van Tuong Pham +13
Magnetic skyrmions are topological spin textures which are envisioned as nanometre scale information carriers in magnetic memory and logic devices. The recent demonstration of room…
Direct observation of the perpendicular shape anisotropy and thermal stability of p-STT-MRAM nano-pillars
Trevor P. Almeida, Steven Lequeux, Alvaro Palomino +6
Perpendicular shape anisotropy (PSA) offers a practical solution to downscale spin-transfer torque Magnetic Random-Access Memory (STT-MRAM) beyond the sub-20 nm technology node whi…
Probing domain walls in cylindrical magnetic nanowires with electron holography
Michal Staňo, Ségolène Jamet, Jean-Christophe Toussaint +5
We probe magnetic domain walls in cylindrical soft magnetic nanowires using electron holography. We detail the modelling of expected contrast for both transverse and Bloch point do…
Micromagnetic study of flux-closure states in Fe dots using quantitative Lorentz Microscopy
Aurélien Masseboeuf, Fabien Cheynis, Olivier Fruchart +3
A micromagnetic study of epitaxial micron-sized iron dots is reported through the analysis of Fresnel contrast in Lorentz Microscopy. Their use is reviewed and developed through an…
Asymmetric hysteresis of Néel caps in flux-closure magnetic dots
Olivier Fruchart, Nicolas Rougemaille, Azzedine Bendounan +8
We investigated with XMCD-PEEM magnetic imaging the magnetization reversal processes of Néel caps inside Bloch walls in self-assembled, micron-sized Fe(110) dots with flux-closure…
Magnetic bubbles in FePd thin films near saturation
Thomas Jourdan, Aurélien Masseboeuf, Alain Marty +2
The structure of domain walls delimiting magnetic bubbles in L10 FePd thin layers is described on the basis of Lorentz transmission electron microscopy (LTEM) and multiscale magnet…
