Systematic study of anisotropic magnetoresistance in (Ga,Mn)As
Original language description
We systematically study the anisotropic magnetoresistance (AMR) on a series of optimizedn(Ga,Mn)As samples. The crystalline and non-crystalline contributions to the AMR were separatednand an apparent higher-order term (of six-fold symmetry) was identified to be an artefactnresulting from the presence of magnetic anisotropy of the material and of the residual fields ofnexternal superconducting magnets. In the broad range of nominal Mn concentrations from 2%nto 11%, we find the non-crystalline contribution to dominate, although the crystalline termsnbecome relatively more important for higher doping levels. We compare the AMR magnitudenwith the Boltzmann transport calculations based on the kp mean-field kinetic-exchange model.
