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…
Probing punctual magnetic singularities during magnetization process in FePd films
Aurélien Masseboeuf, Thomas Jourdan, Frédéric Lançon +2
We report the use of Lorentz microscopy to observe the domain wall structure during the magnetization process in FePd thin foils. We have focused on the magnetic structure of domai…
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…
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…
Quantitative Observation of Magnetic Flux Distribution in New Magnetic Films for Future High Density Recording Media
Aurélien Masseboeuf, A. Marty, Pascale Bayle-Guillemaud +2
Off-axis electron holography was used to observe and quantify the magnetic microstructure of a perpendicular magnetic anisotropic (PMA) recording media. Thin foils of PMA materials…
