Enhanced THz emission from spintronic Fe/Pt emitters through crystal growth optimization
Agne Ciuciulkaite, Oliver Gueckstock, Anna Ravensburg +6
We investigate the THz emission characteristics of ferromagnetic/non-magnetic metallic heterostructures, focusing on thin Fe/Pt bilayers. In particular, we report on the impact of…
Frequency-independent terahertz anomalous Hall effect in DyCo, CoFe and GdFe thin films from DC to 40 THz
Tom S. Seifert, Ulrike Martens, Florin Radu +11
The anomalous Hall effect (AHE) is a fundamental spintronic charge-to-charge-current conversion phenomenon and closely related to spin-to-charge-current conversion by the spin Hall…
High-throughput techniques for measuring the spin Hall effect
Markus Meinert, Björn Gliniors, Oliver Gueckstock +6
The spin Hall effect in heavy-metal thin films is routinely employed to convert charge currents into transverse spin currents and can be used to exert torque on adjacent ferromagne…
Broadband terahertz probes of anisotropic magnetoresistance disentangle extrinsic and intrinsic contributions
Lukáš Nadvorník, Martin Borchert, Liane Brandt +10
Anisotropic magnetoresistance (AMR) is a ubiquitous and versatile probe of magnetic order in contemporary spintronics research. Its origins are usually ascribed to extrinsic effect…
Ultrafast photocurrents in MoSe probed by terahertz spectroscopy
Denis Yagodkin, Lukas Nadvornik, Oliver Gueckstock +3
We use the terahertz (THz) emission spectroscopy to study femtosecond photocurrent dynamics in the prototypical 2D semiconductor, transition metal dichalcogenide MoSe. We ident…
Energy Transfer within the Hydrogen Bonding Network of Water Following Resonant Terahertz Excitation
Hossam Elgabarty, Tobias Kampfrath, Douwe Jan Bonthuis +7
Energy dissipation in water is very fast and more efficient than in many other liquids. This behavior is commonly attributed to the intermolecular interactions associated with hydr…
Phase-resolved Detection of Ultrabroadband THz Pulses inside a Scanning Tunneling Microscope Junction
Melanie Müller, Natalia Martín Sabanés, Tobias Kampfrath +1
Coupling phase-stable single-cycle terahertz (THz) pulses to scanning tunneling microscope (STM) junctions enables spatio-temporal imaging with femtosecond temporal and Ångstrom sp…
