Ab initio investigation of the AlN:Er system
Th. Pavloudis, Valérie Brien, Joseph Kioseoglou
In the present study an ab initio investigation on the AlN:Er system for concentrations of Er ranging from 0.78 to 12.5 % is presented. The crystallographic localisation of the rar…
Erbium location into AlN films as probed by spatial resolution experimental techniques
Valerie Brien, Pascal Boulet
This paper presents a thorough experimental investigation of erbium-doped aluminium nitride thin films prepared by R.F. magnetronsputtering, coupling Scanning Transmission Electron…
Influence of the magnetron power on the Er-related photoluminescence of AlN:Er films prepared by magnetron sputtering
Syed Sajjad Hussain, Valerie Brien, Hervé Rinnert +1
The effect of magnetron power on the room temperature 1.54 m infra-red photoluminescence intensity of erbium doped AlN films grown by r. f. magnetron sputtering, has been studie…
Phase-Change Control of Interlayer Exchange Coupling
Xiaofei Fan, Guodong Wei, Xiaoyang Lin +8
Changing the interlayer exchange coupling between magnetic layers in-situ is a key issue of spintronics, as it allows for the optimization of properties that are desirable for appl…
Ultra-low magnetic damping in Co 2 Mn-based Heusler compounds: promising materials for spintronic
C Guillemard, S. Petit-Watelot, L. Pasquier +8
The prediction of ultra-low magnetic damping in Co 2 MnZ Heusler half-metal thin-film magnets is explored in this study and the damping response is shown to be linked to the underl…
Correlations between stacked structures and weak itinerant magnetic properties of La Y Ni compounds
Valérie Paul-Boncour, Jean-Claude Crivello, Nicolas Madern +5
Hexagonal LaNi and rhombohedral YNi are weak itinerant antiferromagnet (wAFM) and ferromagnet (wFM), respectively. The crystal structure and magnetic properties of…
