Ruiz Gómez, Sandra ; Pérez García, Lucas ; Mascaraque Susunaga, Arantzazu ; Quesada, Adrian ; Prieto, Pilar ; Palacio, Irene ; Martín García, Laura ; Foerster, Michael ; Aballe, Lucía ; Figuera, Juan de la | Royal Society of Chemistry | 2018-03-28We have grown high quality magnetite microcrystals free from antiphase boundaries on Ru(0001) by reactive molecular beam epitaxy, conserving bulk magnetic properties below 20 nm thickness. Magnetization vector maps are obtained by X-ray spectrom[...]texto impreso
Santos, Benito ; Gallego, Silvia ; Mascaraque Susunaga, Arantzazu ; McCarty, Kevin F. ; Quesada, Adrian ; Alpha, N'Diaye T. ; Schmid, Andreas K. ; Figuera, Juan de la | American Physical Society | 2012-04-04Imaging the change in the magnetization vector in real time by spin-polarized low-energy electron microscopy, we observed a hydrogen-induced, reversible spin-reorientation transition in a cobalt bilayer on Ru(0001). Initially, hydrogen sorption [...]texto impreso
Martín García, Laura ; Quesadab, Adrian ; Pérez García, Lucas ; Foerster, Michael ; Aballe, Lucía ; Figuera, Juan de la | Elsevier | 2016Mixed iron-cobalt oxides have been grown on a Ru(0001) single crystal substrate by reactive molecular beam epitaxy. The growth has been followed by low-energy electron microscopy and diffraction. Chemical characterization has been performed by s[...]texto impreso
Monti, Matteo ; Santos, Benito ; Mascaraque Susunaga, Arantzazu ; Rodríguez de la Fuente, Óscar ; Nino, Miguel Angel ; Mentes, Tevfik Onur ; Locatelli, Andrea ; McCarty, Kevin F. ; Marco, José F. ; Figuera, Juan de la | American Physical Society | 2012-01-11The oldest known magnetic material, magnetite, is of current interest for use in spintronics as a thin film. An open question is how thin can magnetite films be and still retain the robust ferrimagnetism required for many applications. We have g[...]texto impreso
Martín García, Laura ; Chen, Gong ; Montaña, Yaiza ; Mascaraque Susunaga, Arantzazu ; Pabón, Beatriz M. ; Schmid, Andreas K. ; Figuera, Juan de la | Nature Publishing Group | 2018-04-16The structure of magnetic domains, i.e. regions of uniform magnetization separated by domain walls, depends on the balance of competing interactions present in ferromagnetic (or ferrimagnetic) materials. When these interactions change then domai[...]texto impreso
Ruiz Gómez, Sandra ; Mascaraque Susunaga, Arantzazu ; Pérez García, Lucas ; Foerster, Michael ; Aballe, Lucía ; Proenca, M. P. ; Lucas, Irene ; Prieto, José Luis ; Figuera, Juan de la ; Quesada, Adrian | Nature Publishing Group | 2018-11-12The precise control and stabilization of magnetic domain walls is key for the development of the next generation magnetic nano-devices. Among the multitude of magnetic configurations of a magnetic domain wall, topologically protected states are [...]texto impreso
Santos, B. ; Loginova, E. ; Mascaraque Susunaga, Arantzazu ; Schmid, A. K. ; McCarty, K. F. ; Figuera, Juan de la | Institute of Physics | 2009-08-05We have grown epitaxial films a few atomic layers thick of iron oxides on ruthenium. We characterize the growth by low energy electron microscopy. Using selected-area diffraction and intensity-versus-voltage spectroscopy, we detect two distinct [...]texto impreso
Ruiz Gómez, Sandra ; Pérez García, Lucas ; Mandziak, Anna ; Figuera, Juan de la ; Delgado Soria, Guiomar ; Prieto Recio, Pilar ; Quesada, Adrian ; Foerster, Michael ; Aballe, Lucía | Nature Publishing Group | 2018-12-19We demonstrate the preparation of ultrathin Fe-rich nickel ferrite (NFO) islands on a metal substrate. Their nucleation and growth are followed in situ by low-energy electron microscopy (LEEM). A comprehensive characterization is performed combi[...]texto impreso
Mascaraque Susunaga, Arantzazu ; Mentes, T. Onur ; McCarty, Kevin F ; Marcos, José ; Schmid, Andreas K. ; Locatelli, Andrea ; Figuera, Juan de la | Institute of Physics | 2011-08-03For the non-magnetic system of Ag films on Ru(0001), we have measured the circular dichroism of photoelectrons emitted along the surface normal, the geometry typically used in photoemission electron microscopy. Photoemission spectra were acquire[...]
