Dissipationless transport signature of topological nodal lines
Arthur Veyrat, Klaus Koepernik, Louis Veyrat +12
Topological materials, such as topological insulators or semimetals, usually not only reveal the nontrivial properties of their electronic wavefunctions through the appearance of s…
Disorder-induced coupling of Weyl nodes in WTe
Steffen Sykora, Johannes Schoop, Lukas Graf +7
The finite coupling between Weyl nodes due to residual disorder is investigated by magnetotransport studies in WTe. The anisotropic scattering of quasiparticles is evidenced fr…
Meta-magnetism of weakly-coupled antiferromagnetic topological insulators
Aoyu Tan, Valentin Labracherie, Narayan Kunchur +6
The magnetic properties of the van der Waals magnetic topological insulators MnBiTe and MnBiTe are investigated by magneto-transport measurements. We evidence that…
Thickness dependence of the anomalous Nernst effect and the Mott relation of Weyl-semimetal Co2MnGa thin films
Gyu-Hyeon Park, Helena Reichlova, Richard Schlitz +12
We report a robust anomalous Nernst effect in Co2MnGa thin films in the thickness regime between 20 and 50 nm. The anomalous Nernst coefficient varied in the range of -2.0 to -3.0…
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…
All Electrical Access to Topological Transport Features in MnPtSn Films
Richard Schlitz, Peter Swekis, Anastasios Markou +7
The presence of non-trivial magnetic topology can give rise to non-vanishing scalar spin chirality and consequently a topological Hall or Nernst effect. In turn, topological transp…
Mapping of the energetically lowest exciton in bulk -HfS
Carsten Habenicht, Lorenzo Sponza, Roman Schuster +2
By combining electron energy-loss spectroscopy and state-of-the-art computational methods, we were able to provide an extensive picture of the excitonic processes in -HfS.…
Large anomalous Nernst effect in thin films of the Weyl semimetal Co2MnGa
Helena Reichlova, Richard Schlitz, Sebastian Beckert +11
The magneto-thermoelectric properties of Heusler compound thin films are very diverse. Here, we discuss the anomalous Nernst response of CoMnGa thin films. We systematically st…
Anomalous Nernst effect and field-induced Lifshitz transition in Weyl semimetals TaP and TaAs
Federico Caglieris, Christoph Wuttke, Steffen Sykora +5
The discovery of Weyl fermions in transition metal monoarsenides/phosphides without inversion symmetry represents an exceptional breakthrough in modern condensed matter physics. Ho…
Spin-Hall-Active Platinum Thin Films Grown Via Atomic Layer Deposition
Richard Schlitz, Akinwumi Abimbola Amusan, Michaela Lammel +7
We study the magnetoresistance of yttrium iron garnet/Pt heterostructures in which the Pt layer was grown via atomic layer deposition (ALD). Magnetotransport experiments in three o…
Evolution of the Spin Hall Magnetoresistance in CrO/Pt bilayers close to the Néel temperature
Richard Schlitz, Tobias Kosub, Andy Thomas +4
We study the evolution of magnetoresistance with temperature in thin film bilayers consisting of platinum and the antiferromagnet CrO with its easy axis out of the plane. W…
Spin waves in coupled YIG/Co heterostructures
Stefan Klingler, Vivek Amin, Stephan Geprägs +9
We investigate yttrium iron garnet (YIG)/cobalt (Co) heterostructures using broadband ferromagnetic resonance (FMR). We observe an efficient excitation of perpendicular standing sp…
Spin Hall magnetoresistance in antiferromagnet/heavy-metal heterostructures
Johanna Fischer, Olena Gomonay, Richard Schlitz +8
We investigate the spin Hall magnetoresistance in thin film bilayer heterostructures of the heavy metal Pt and the antiferromagnetic insulator NiO. While rotating an external magne…
Suppression of scattering in quantum confined 2D-helical Dirac systems
Joseph Dufouleur, Emmanouil Xypakis, Bernd Büchner +2
Transport properties of disordered quantum confined helical Dirac systems are investigated in the large energy limit. As long as the 2D transport length is larger than the perimete…
