Experimental Signatures of Topological Transport in Polycrystalline FeSi Thin Films
R. Mantovan, A. Bozhko, V. Zhurkin +5
Iron monosilicide -FeSi has recently been predicted to host nontrivial topological states, yet experimental evidence remains scarce. Here we report transport signatures of Weyl…
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…
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…
Terahertz time-domain signatures of the inverse Edelstein effect in topological-insulator|ferromagnet heterostructures
Genaro Bierhance, Chihun In, Enzo Rongione +14
Three-dimensional topological insulators possess topologically protected surface states with spin-momentum locking, which enable spin-charge-current interconversion (SCI) by the in…
