Summary:Authors report on an effect of shape anisotropy on the magnetic configuration of the magnetic semiconductor (Ga, Mn)As using magnetoresistance (MR) measurements. A substantial change in the MR curve occurs for a wire sample with a width of 0.8 mum, in which the shape anisotropy along the wire axis is more significant than the intrinsic magnetic anisotropy. Moreover, the magnetic configuration of the wire sample depends on the hole concentration which has an influence on the cubic, uniaxial and shape anisotropy, being reflected by the hole induced ferromagnetic characteristics of (Ga, Mn)As. 16 refs.
