Structure and magnetism of the -FeO(111) surface
Ivan Bernal-Villamil, Silvia Gallego
Based on ab initio calculations we determine the features and relative stability of different models proposed to describe the -FeO(111) reconstruction. Our results su…
Order-disorder phase transition on the (100) surface of magnetite
Norman C. Bartelt, Shu Nie, Elena Starodub +5
Using low-energy electron diffraction, we show that the room-temperature reconstruction of FeO(100) reversibly disorders at 450 $^…
Hydrogen-induced reversible spin-reorientation transition and magnetic stripe domain phase in bilayer Co on Ru(0001)
Benito Santos, Silvia Gallego, Arantzazu Mascaraque +5
Imaging the change in the magnetization vector in real time by spin-polarized low-energy electron microscopy, we observed a hydrogen-induced, reversible spin-reorientation transiti…
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…
Friedel oscillations induced surface magnetic anisotropy
A. Szilva, S. Gallego, M. C. Munoz +3
We present detailed numerical studies of the magnetic anisotropy energy of a magnetic impurity near the surface of metallic hosts (Au and Cu), that we describe in terms of a realis…
