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…
Spontaneous anomalous Hall effect arising from an unconventional compensated magnetic phase in a semiconductor
R. D. Gonzalez Betancourt, J. Zubáč, R. J. Gonzalez-Hernandez +12
The anomalous Hall effect, commonly observed in metallic magnets, has been established to originate from the time-reversal symmetry breaking by an internal macroscopic magnetizatio…
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…
Atomic Layer Deposition of Yttrium Iron Garnet Thin Films for 3D Magnetic Structures
M. Lammel, D. Scheffler, D. Pohl +11
A wide variety of new phenomena such as novel magnetization configurations have been predicted to occur in three dimensional magnetic nanostructures. However, the fabrication of su…
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…
Spin Hall magnetoresistance in heterostructures consisting of noncrystalline paramagnetic YIG and Pt
Michaela Lammel, Richard Schlitz, Kevin Geishendorf +8
The spin Hall magnetoresistance (SMR) effect arises from spin-transfer processes across the interface between a spin Hall active metal and an insulating magnet. While the SMR respo…
Magnetoresistance and anomalous Hall effect in micro-ribbons of the magnetic Weyl semimetal CoSnS
Kevin Geishendorf, Richard Schlitz, Praveen Vir +5
Magnetic Weyl semimetals exhibit intriguing transport phenomena due to their non-trivial band structure. Recent experiments in bulk crystals of the shandite-type CoSnS…
