Nodeless Hybridization as Proof of Trivial Topology in Samarium Hexaboride
E. D. L. Rienks, P. Hlawenka, J. Sánchez-Barriga +13
Calculations unanimously predict samarium hexaboride to be a topological Kondo insulator, the first topological insulator driven by strong electron correlation. As of today it appe…

We measured high resolution Cu edge resonant inelastic x-ray scattering (RIXS) of the undoped cuprates LaCuO, SrCuOCl, CaCuO and NdBaCuO.…
Nonresonant microwave absorption in epitaxial La-Sr-Mn-O films and its relation to colossal magnetoresistance
M. Golosovsky, P. Monod, P. K. Muduli +3
We study magnetic-field-dependent nonresonant microwave absorption and dispersion in thin LaSrMnO films and show that it originates from the colossal magnetor…
Towards magnetic control of magnetite

High quality stoichiometric magnetite (Fe3O4) films grown by infrared pulsed laser deposition (IR-PLD) on different surfaces were investigated in order to study the influence of th…
Magnetic properties of pseudomorphic epitaxial films of Pr_{0.7}Ca_{0.3}MnO_3 under different biaxial tensile stresses
A. Geddo Lehmann, F. Congiu, N. Lampis +4
In order to analyse the effect of strain on the magnetic properties of narrow-band manganites, the temperature and field dependent susceptibilities of about 8.5 nm thick epitaxial…
Direct determination of Spin-Orbit torque by using dc current-voltage characteristics

Origin of the Large Perpendicular Magnetic Anisotropy in Nanometer-thick Epitaxial Graphene/Co/Heavy Metal Heterostructures
M. Blanco-Rey, P. Perna, A. Gudin +13
A combination of theoretical modelling and experiments reveals the origin of the large perpendicular magnetic anisotropy (PMA) that appears in nanometer-thick epitaxial Co films in…
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…
