Abstract
The anisotropy of the magnetoresistance of single crystalline Gd 5Si2Ge2 was investigated. The first principles calculations demonstrate that a structural modification is responsible for the anisotropy of the magnetoresistance. The absolute values measured along the [100] and [010] directions exceed those parallel to the [001] direction by more than 60%. The observed magnetoresistance of single crystalline Gd 5Si2Ge2 was found to be negative and strongly anisotropic.
