Journal ArticleDOI
Phase-locking of magnetic vortices mediated by antivortices.
Antonio Ruotolo,Vincent Cros,Benoit Georges,A. Dussaux,Julie Grollier,Cyrile Deranlot,R. Guillemet,Karim Bouzehouane,Stéphane Fusil,Albert Fert +9 more
TL;DR: It is found that vortices can interact with each other through the mediation of antivortices, leading to synchronization when they are closely spaced, making the system attractive for electronic device integration.
Journal ArticleDOI
Effect of the magnetic order on the room-temperature band-gap of Mn-doped ZnO thin films
Xiao Li Wang,Chun Yan Luan,Qi Shao,Alina Pruna,Chi Wah Leung,Rolf Lortz,Juan Antonio Zapien,Antonio Ruotolo +7 more
TL;DR: In this article, the exchange interaction between localized magnetic moments mediated by free charge carriers is responsible for a non-monotonic dependence of the low-temperature energy band-gap in dilute magnetic semiconductors.
Journal ArticleDOI
Commensurability and chaos in magnetic vortex oscillations
Sébastien Petit-Watelot,Joo-Von Kim,Antonio Ruotolo,Antonio Ruotolo,Ruben Otxoa,Karim Bouzehouane,Julie Grollier,Arne Vansteenkiste,Ben Van de Wiele,Vincent Cros,Thibaut Devolder +10 more
TL;DR: In this paper, the authors report on an experimental observation of periodic core reversal during self-sustained vortex gyration in a magnetic nanocontact system and show that commensurate phase-locked and incommensurate chaotic states are possible, resulting in Devil's staircases with driving currents.
Journal ArticleDOI
High-quality all-oxide Schottky junctions fabricated on heavily doped Nb: Sr Ti O 3 substrates
TL;DR: In this paper, the electrical properties of epitaxial Schottky junctions have been investigated and it has been shown that high quality oxide-based junctions maintain a highly rectifying behavior for doping concentration of the semiconductor larger than 10−20.
Journal ArticleDOI
Enhanced photocatalytic performance of ZnO nanostructures by electrochemical hybridization with graphene oxide
TL;DR: In this paper, the properties of hybrid ZnO nanostructures were investigated by scanning electron microscopy, X-ray diffraction, Raman, Fourier-Transform Infrared and Xray photoelectron spectroscopy techniques and photocatalytic measurements.
