Abstract
- Anisotropic magnetoresistance (AMR) effects in Co<subscript>x</subscript>(Mn<subscript>0.44</subscript>Ga<subscript>0.56</subscript>)<subscript>100−x</subscript> 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 // Co<subscript>2</subscript>MnGa[100] and negative for I // Co<subscript>2</subscript>MnGa[110] 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.
