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…
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…
Coinage-metal capping effects on the spin-reorientations of Co/Ru(0001)
Farid el Gabaly, Kevin F. McCarty, Andreas K. Schmid +5
Thin films of Co/Ru(0001) are known to exhibit an unusual spin reorientation transition (SRT) coupled to the completion of Co atomic layers for Co thicknesses under 4 layers. By me…
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…
Imaging Spin Reorientation Transitions in Consecutive Atomic Co layers
Farid El Gabaly, Silvia Gallego, Carmen Munoz +6
By means of spin-polarized low-energy electron microscopy (SPLEEM) we show that the magnetic easy-axis of one to three atomic-layer thick cobalt films on ruthenium crystals changes…
Magnetism and half-metallicity at the O surfaces of ceramic oxides
S. Gallego, J. I. Beltran, J. Cerda +1
The occurence of spin-polarization at ZrO, AlO and MgO surfaces is proved by means of \textit{ab-initio} calculations within the density functional theory. Large…
