Current-induced spin torques on single GdFeCo magnetic layers
David Céspedes-Berrocal, Heloïse Damas, Sébastien Petit-Watelot +16
Spintronics exploits spin-orbit coupling (SOC) to generate spin currents, spin torques, and, in the absence of inversion symmetry, Rashba, and Dzyaloshinskii-Moriya interactions (D…
Quantitative imaging of hybrid chiral spin textures in magnetic multilayer systems by Lorentz microscopy
K. Fallon, S. McVitie, W. Legrand +5
Chiral magnetic textures in ultrathin perpendicularly magnetised multilayer film stacks with an interfacial Dzyaloshinskii-Moriya interaction have been the focus of much research r…
Engineering Large Anisotropic Magnetoresistance in La0.7Sr0.3MnO3 Films at Room Temperature
Paolo Perna, Davide Maccariello, Fernando Ajejas +6
The magnetoresistance (MR) effect is widely employed in technologies that pervade our world from magnetic reading heads to sensors. Diverse contributions to MR, such as anisotropic…
Dzyaloshinskii-Moriya interaction at disordered interfaces from ab initio theory: robustness against intermixing and tunability through dusting
Bernd Zimmermann, William Legrand, Davide Maccariello +4
The Dzyaloshinskii-Moriya interaction (DMI), which is essential for the stabilization of topologically non-trivial chiral magnetic textures such as skyrmions, is particularly stron…
Modeling the shape of axisymmetric skyrmions in magnetic multilayers
William Legrand, Nathan Ronceray, Nicolas Reyren +3
We present a comprehensive micromagnetic model of isolated axisymmetric skyrmions in magnetic multilayers with perpendicular anisotropy. Most notably, the essential role of the int…
Hybrid chiral domain walls and skyrmions in magnetic multilayers
William Legrand, Jean-Yves Chauleau, Davide Maccariello +6
Noncollinear spin textures in ferromagnetic ultrathin films are currently the subject of renewed interest since the discovery of the interfacial Dzyaloshinskii-Moriya interaction (…
Interfacial exchange coupling induced chiral symmetry-breaking of Spin-Orbit effects
P. Perna, F. Ajejas, D. Maccariello +6
We demonstrate that the interfacial exchange coupling in ferromagnetic/antiferromagnetic (FM/AFM) systems induces symmetry-breaking of the Spin-Orbit (SO) effects. This has been do…
A transmission electron microscope study of Néel skyrmion magnetic textures in multilayer thin film systems with large interfacial chiral interaction
S. McVitie, S. Hughes, K. Fallon +12
Skyrmions in ultrathin ferromagnetic metal (FM)/heavy metal (HM) multilayer systems produced by conventional sputtering methods have recently generated huge interest due to their a…
Chirality in magnetic multilayers probed by the symmetry and the amplitude of dichroism in X-ray resonant magnetic scattering
J. -Y. Chauleau, W. Legrand, N. Reyren +7
Chirality in condensed matter is now a topic of the utmost importance because of its significant role in the understanding and mastering of a large variety of new fundamental physi…
Room-temperature current-induced generation and motion of sub-100nm skyrmions
William Legrand, Davide Maccariello, Nicolas Reyren +7
Magnetic skyrmions are nanoscale windings of the spin configuration that hold great promise for technology due to their topology-related properties and extremely reduced sizes. Aft…
Persistent photoconductivity in 2-dimensional electron gases at different oxide interfaces
Emiliano Di Gennaro, Umberto Scotti di Uccio, Carmela Aruta +10
We report on the transport characterization in dark and under light irradiation of three different interfaces: LaAlO3/SrTiO3, LaGaO3/SrTiO3, and the novel NdGaO3/SrTiO3 heterostruc…
Reversible and Persistent Photoconductivity at the NdGaO3/SrTiO3 Conducting Interface
Umberto Scotti di Uccio, Carmela Aruta, Claudia Cantoni +10
The interface between the band gap insulators LaAlO3 and SrTiO3 is known to host a highly mobile two-dimensional electron gas. Here we report on the fabrication and characterizatio…
Electron transfer and ionic displacements at the origin of the 2D electron gas at the LAO/STO interface: Direct measurements with atomic-column spatial resolution
C. Cantoni, J. Gazquez, F. Miletto Granozio +8
The discovery that the interface between two band gap insulators LaAlO3 and SrTiO3 is highly conducting has raised an enormous interest in the field of oxide electronics. The LAlO3…
Conducting interfaces between band insulating oxides: the LaGaO3/SrTiO3
Paolo Perna, Davide Maccariello, Milan Radovic +9
We show that the growth of the heterostructure LaGaO3/SrTiO3 yields the formation of a highly conductive interface. Our samples were carefully analyzed by high resolution electron…
