Room temperature p-induced surface ferromagnetism
Guntram Fischer, Nadiezhda Sanchez, Waheed A. Adeagbo +6
We prove a spontaneous magnetization of the oxygen-terminated ZnO (0001) surface by utilizing a multi-code, SIESTA and KKR, first-principles approach, involving both LSDA+U and sel…
Reversible enhancement of the magnetism of ultrathin Co films by H adsorption
Silvia Gallego, Nadia Sanchez, Sofia Martin +2
By means of ab initio calculations, we have investigated the effect of H adsorption in the structural, electronic and magnetic properties of ultrathin Co films on Ru(0001). Our cal…
Tuning surface metallicity and ferromagnetism by hydrogen adsorption at the polar ZnO(0001) surface
N. Sanchez, S. Gallego, J. Cerdá +1
The adsorption of hydrogen on the polar Zn-ended ZnO(0001) surface has been investigated by density functional {\it ab-initio} calculations. An on top H(1x1) ordered overlayer with…
Magnetic states at the Oxygen surfaces of ZnO and Co-doped ZnO
N. Sanchez, S. Gallego, M. C. Munoz
First principles calculations of the O surfaces of Co-ZnO show that substitutional Co ions develop large magnetic moments which long-range coupling depends on their mutual distance…
