Terahertz magneto-photocurrents in the topological insulator BiSe probe its topological surface states
Chihun In, Genaro Bierhance, Deepti Jain +5
We study ultrafast magneto-photocurrents in a three-dimensional topological insulator. For this purpose, we excite (InBi)Se thin films with a femtosecond laser…
Transition Metal Dichalcogenide 1T-MoTe Nanoscale Films as Spin Pumping Platforms
Emanuele Longo, Pinakapani Tummala, M. Belli +5
Transition metal dichalcogenides (TMDs) have emerged as a promising class of materials for spintronics, with the aim of promoting efficient spin-charge conversion (SCC) in TMD/ferr…
Atomic-scale Origin of Interfacial Dzyaloshinskii--Moriya Interaction in Pt/Fe/Au
Emanuele Longo, Gianluca Gubbiotti, Matteo Belli +4
Recent results show remarkable interfacial--Dzyaloshinskii--Moriya interaction (i-DMI) in magnetic heterostructures composed of relatively thick Fe thin films ( nm). To inve…
Probing the quantum metric of 3D topological insulators
Giacomo Sala, Emanuele Longo, Maria Teresa Mercaldo +5
The surface states of 3D topological insulators possess geometric structures that imprint distinctive signatures on electronic transport. A prime example is the Berry curvature, wh…
