The full Heusler compound Co₂MnGa belongs to the family of Weyl-II-semimetals. Large anomalous Nernst effect has been observed in Co2 MnGa [1] and it was attributed to non-vanishing Berry curvature close to the Weyl points making the material a promising candidate for study of exotic transport phenomena. In this work, I focus on the anisotropic magnetoresistance (AMR) in Co₂MnGa thin films. The AMR is measured in a series of samples of various thicknesses t at different temperatures T allowing for...
