Unidirectional motion of topological defects mediating continuous rotation processes
Marisel Di Pietro Martínez, Luke Alexander Turnbull, Jeffrey Neethirajan +9
Topological defects play a critical role across many fields, mediating phase transitions and macroscopic behaviors as they move through space. Their role as robust information carr…
Helicity-dependent Ultrafast Photocurrents in Weyl Magnet MnSn
Dominik Hamara, Gunnar F. Lange, Farhan Nur Kholid +4
We present an optical pump-THz emission study on non-collinear antiferromagnet MnSn. We show that MnSn acts as a source of THz radiation when irradiated by femtosecond lase…
Spin-voltage-driven efficient terahertz spin currents from the magnetic Weyl semimetals CoMnGa and CoMnAl
Genaro Bierhance, Anastasios Markou, Oliver Gueckstock +7
Magnetic Weyl semimetals are an emerging material class that combines magnetic order and a topologically non-trivial band structure. Here, we study ultrafast optically driven spin…
Anomalous and topological Hall effects in epitaxial thin films of the noncollinear antiferromagnet MnSn
James M. Taylor, Anastasios Markou, Edouard Lesne +6
Noncollinear antiferromagnets with a D0 (space group = 194, P6/mmc) hexagonal structure have garnered much attention for their potential applications in topological sp…
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…
Imaging and writing magnetic domains in the non-collinear antiferromagnet MnSn
Helena Reichlova, Tomas Janda, Joao Godinho +12
Harnessing the unique properties of non-collinear antiferromagnets (AFMs) will be essential for exploiting the full potential of antiferromagnetic spintronics. Indeed, many of the…
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…
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…
