Anisotropic magnetoresistance in altermagnetic MnTe
Ruben Dario Gonzalez Betancourt, Jan Zubáč, Kevin Geishendorf +12
Recently, MnTe was established as an altermagnetic material that hosts spin-polarized electronic bands as well as anomalous transport effects like the anomalous Hall effect. In add…
Observation of an unexpected negative magnetoresistance in magnetic Weyl semimetal CoSnS
Ali G. Moghaddam, Kevin Geishendorf, Richard Schlitz +8
Time-reversal symmetry breaking allows for a rich set of magneto-transport properties related to electronic topology. Focusing on the magnetic Weyl semimetal CoSnS, we…
Optically gated terahertz-field-driven switching of antiferromagnetic CuMnAs
J. J. F. Heitz, L. Nádvorník, V. Balos +11
We show scalable and complete suppression of the recently reported terahertz-pulse-induced switching between different resistance states of antiferromagnetic CuMnAs thin films by u…
Fast fourier transform and multi-Gaussian fitting of XRR data to determine the thickness of ALD grown thin films within the initial growth regime
Michaela Lammel, Kevin Geishendorf, Marisa Choffel +4
While a linear growth behavior is one of the fingerprints of textbook atomic layer deposition processes, the growth often deviates from that behavior in the initial regime, i.e. th…
The impact of metallic contacts on spin-polarized photocurrents in topological insulator nanowires
Nina Meyer, Kevin Geishendorf, Jakob Walowski +2
Recently, a new quantum phase, the topological insulator, has been vividly investigated in a variety of materials. Its unique bandstructure allows for optical generation and contro…
Photocurrent measurements in topological insulator nanowires
N. Meyer, K. Geishendorf, J. Walowski +2
Circular photogalvanic currents are a promising new approach for spin-optoelectronics. To date, such currents have only been induced in topological insulator flakes or extended fil…
