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…
How many bits may fit in a single magnetic dot? XMCD-PEEM evidences the switching of Néel caps inside Bloch domain walls
Fabien Cheynis, Aurélien Masseboeuf, Olivier Fruchart +5
Data storage relies on the handling of two states, called bits. The market of mass storage is currently still dominated by magnetic technology, hard disk drives for the broad publi…
Dimensionality cross-over in magnetism: from domain walls (2D) to vortices (1D)
Aurélien Masseboeuf, Olivier Fruchart, Jean-Christophe Toussaint +5
Dimensionality cross-over is a classical topic in physics. Surprisingly it has not been searched in micromagnetism, which deals with objects such as domain walls (2D) and vortices…
Lorentz microscopy mapping for domain walls structure study in L1 FePd thin films
Aurélien Masseboeuf, Christophe Gatel, Pascale Bayle-Guillemaud +2
Thin film alloys with perpendicular anisotropy were studied using Lorentz Transmission Electron Microscopy (LTEM). This work focuses on the configuration of domain walls and demons…
Tunable magnetic properties of arrays of Fe(110) nanowires grown on kinetically-grooved W(110) self-organized templates
Bogdana Borca, Olivier Fruchart, Evaggelos Kritsikis +5
We report a detailed magnetic study of a new type of self-organized nanowires disclosed briefly previously [B. Borca et al., Appl. Phys. Lett. 90, 142507 (2007)]. The templates, pr…
Contacting individual Fe(110) dots in a single electron-beam lithography step
Fabien Cheynis, Helge Haas, Thierry Fournier +4
We report on a new approach, entirely based on electron-beam lithography technique, to contact electrically, in a four-probe scheme, single nanostructures obtained by self-assembly…
