Terahertz spin-current transparency through rough interfaces
JiÅà Jechumtál, Jakub Zázvorka, OndÅej Novák +8
Spin transport across interfaces is critical for spintronic devices, yet remains difficult to probe on ultrafast timescales. We use terahertz emission spectroscopy on Co|Pt heteros…
Spin-to-charge-current conversion in altermagnetic candidate RuO probed by terahertz emission spectroscopy
J. Jechumtál, O. Gueckstock, K. Jasenský +19
Using the THz emission spectroscopy, we investigate ultrafast spin-to-charge current conversion in epitaxial thin films of the altermagnetic candidate RuO. We perform a quantit…
Observation of terahertz spin-Hall magnetoresistance in the model system
P. KubaÅ¡ÄÃk, R. Schlitz, O. Gueckstock +17
We report the observation of spin Hall magnetoresistance (SMR) in prototypical bilayers of ferrimagnetic yttrium iron garnet (YIG) and platinum in the frequency range from 0 THz to…
Even-in-magnetic field part of transverse resistivity as a probe of magnetic transitions
Antonin Badura, Dominik Kriegner, Eva Schmoranzerová +13
The component of the resistivity tensor corresponding to voltage transverse to both an applied current and a magnetic field can be separated into odd and even parts with…
Exploring the impact of the inverse Faraday effect on all-optical helicity-dependent magnetization switching
M. Kohlmann, L. Vollroth, K. Jäckel +7
All-optical helicity-dependent magnetization switching (AO-HDS) is the quickest data recording technique using only ultrashort laser pulses. FePt grains provide an ideal platform f…
Anisotropy of the anomalous Hall effect in the altermagnet candidate MnSi films
Miina Leiviskä, Javier Rial, AntonÃn Badura +15
Altermagnets are compensated magnets belonging to spin symmetry groups that allow alternating spin polarizations both in the coordinate space of the crystal and in the momentum spa…
