Anisotropic magnetoresistance (AMR) effects in Cox(Mn0.44Ga0.56)100-x epitaxial thin films were investigated in the temperature range of 5-300 K by changing the current (I) direction to the crystal axis and the Co content (x). The AMR ratios were mostly positive for I // Co2MnGa and negative for I // Co2MnGa and showed peak values at x = 49.7 at% for both current directions. AMR ratios calculated from s-d scattering theory, including crystal field effects with density of states information from first-principles calculations, well reproduced experimental features.
