Thermally induced all-optical ferromagnetic resonance in thin YIG films
E. Schmoranzerová, J. Kimák, R. Schlitz +10
All-optical ferromagnetic resonance (AO-FMR) is a powerful tool for local detection of micromagnetic parameters, such as magnetic anisotropy, Gilbert damping or spin stiffness. In…
Anisotropic magneto-thermal transport in CoMnGa thin films
Philipp Ritzinger, Helena Reichlova, Dominik Kriegner +9
Ferromagnetic CoMnGa has recently attracted significant attention due to effects related to non-trivial topology of its band structure, however a systematic study of canonical…
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…
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…
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…
