Unravelling the role of Sm 4f electrons in the magnetism of SmFeO
Danila Amoroso, Bertrand Dupe, Matthieu J. Verstraete
Magnetic rare-earth orthoferrites FeO host a variety of functional properties from multiferroicity and strong magnetostriction, to spin-reorientation transitions and ultrafa…
A pre-time-zero spatiotemporal microscopy technique for the ultrasensitive determination of the thermal diffusivity of thin films
Sebin Varghese, Jake Dudley Mehew, Alexander Block +8
Diffusion is one of the most ubiquitous transport phenomena in nature. Experimentally, it can be tracked by following point spreading in space and time. Here, we introduce a spatio…
Spin-current driven Dzyaloshinskii-Moriya interaction in the multiferroic BiFeO3 from first-principles
Sebastian Meyer, Bin Xu, Matthieu Verstraete +2
The electrical control of magnons opens up new ways to transport and process information for logic devices. In magnetoelectrical multiferroics, the Dzyaloshinskii-Moriya (DM) inter…
Electrical Control of Spin-polarized Topological Currents in Monolayer WTe
Jose H. Garcia, Jinxuan You, Monica García-Mota +6
We evidence the possibility for coherent electrical manipulation of the spin orientation of topologically protected edge states in a low-symmetry quantum spin Hall insulator. By us…
The impact of valley profile on the mobility and Kerr rotation of transition metal dichalcogenides
Thibault Sohier, Pedro M. M. C. de Melo, Zeila Zanolli +1
The transport and optical properties of semiconducting transition metal dichalcogenides around room temperature are dictated by electron-phonon scattering mechanisms within a compl…
High-throughput analysis of Fröhlich-type polaron models
Pedro Miguel M. C. de Melo, Joao C. de Abreu, Bogdan Guster +4
The electronic structure of condensed matter can be significantly affected by the electron-phonon interaction, leading to important phenomena such as electrical resistance, superco…
Spectroscopic signatures of nonpolarons : the case of diamond
Joao C. de Abreu, Jean Paul Nery, Matteo Giantomassi +2
Polarons are quasi-particles made from electrons interacting with vibrations in crystal lattices. They derive their name from the strong electron-vibration polar interaction in ion…
The role of band matching in the proximity effect between a superconductor and a normal metal
Loic Mougel, Patrick M. Buhl, Qili Li +6
We combine density functional theory and scanning tunneling microscopy to study the proximity effects between a bulk Ru(0001) superconductor and an atomically thin overlayer of Co.…
