Terahertz spin-to-charge current conversion in stacks of ferromagnets and the transition-metal dichalcogenide NbSe
Lukáš Nádvorník, Oliver Gueckstock, Lukas Braun +16
Transition-metal dichalcogenides (TMDCs) are an aspiring class of materials with unique electronic and optical properties and potential applications in spin-based electronics. Here…
Circular photogalvanic effects in topological insulator/ferromagnet hybrid structures
T. Schumann, T. Kleinke, L. Braun +12
We study laser driven spin-current effects at ferromagnet/topological-insulator interfaces by two complementary experimental approaches. The DC photocurrent is studied in ferromagn…
Observation of spin Nernst photocurrents in topological insulators
T. Schumann, N. Meyer, G. Mussler +7
The theoretical prediction of topological insulators in 2007 triggered tremendous interest. They are of fundamental interest because of their topological twist in k-space, which co…
Control of oxidation and spin state in a single-molecule junction
Benjamin W. Heinrich, Christopher Ehlert, Nino Hatter +4
The oxidation and spin state of a metal-organic molecule determine its chemical reactivity and magnetic properties. Here, we demonstrate the reversible control of the oxidation and…
Ultrafast photocurrents at the surface of the three-dimensional topological insulator
Lukas Braun, Gregor Mussler, Andrzej Hruban +6
Topological insulators constitute a new and fascinating class of matter with insulating bulk yet metallic surfaces that host highly mobile charge carriers with spin-momentum lockin…
Efficient metallic spintronic emitters of ultrabroadband terahertz radiation
T. Seifert, S. Jaiswal, U. Martens +18
Terahertz electromagnetic radiation is extremely useful for numerous applications such as imaging and spectroscopy. Therefore, it is highly desirable to have an efficient table-top…
Coherent ultrafast spin-dynamics probed in three dimensional topological insulators
F. Boschini, M. Mansurova, G. Mussler +12
Topological insulators are candidates to open up a novel route in spin based electronics. Different to traditional ferromagnetic materials, where the carrier spin-polarization and…
Tuning the magnetic anisotropy of single molecules
Benjamin W. Heinrich, Lukas Braun, Jose I. Pascual +1
The magnetism of single atoms and molecules is governed by the atomic scale environment. In general, the reduced symmetry of the surrounding splits the states and aligns the ma…
Protection of excited spin states by a superconducting energy gap
B. W. Heinrich, L. Braun, J. I. Pascual +1
The latest concepts for quantum computing and data storage envision to address and manipulate single spins. A limitation for single atoms or molecules in contact to a metal surface…
