Role of magnetic exchange interactions in chiral-type Hall effects of epitaxial MnPtSn films

Peter Swekis, Jacob Gayles, Dominik Kriegner +5

Tetragonal Mn-based Heusler compounds feature rich exchange interactions and exotic topological magnetic textures, such as antiskyrmions, complimented by the chiral-type Hall effec…

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…

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…

Topological Hall effect in thin films of MnPtSn

Peter Swekis, Anastasios Markou, Dominik Kriegner +5

Spin chirality in metallic materials with non-coplanar magnetic order can give rise to a Berry phase induced topological Hall effect. Here, we report the observation of a large top…

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…
