However, a systematic study of canonical magnetogalvanic transport effects is missing. Focusing on high quality thin films, here we systematically measure anisotropic magnetoresistance (AMR) and its thermoelectric counterpart anisotropic magnetothermopower (AMTP). We model the AMR data by free energy minimization within the Stoner-Wohlfarth formalism and conclude that both crystalline and noncrystalline components of this magnetotransport phenomenon are present in Co2MnGa. The AMTP is, in comparison to the AMR, large in relative terms, since the Seebeck coefficient Σ0 is small, which is discussed in the context of the Mott rule and of phonon drag. A further analysis of AMTP components is presented.
