Abstract

The structural parameters of ε-FeGe have been determined at ambient conditions using single crystal refinement. Powder diffraction has been carried out to determine structural properties and compressibility for pressures up to 30 GPa and temperatures as low as 82 K. The discontinuous change in the pressure dependence of the shortest Fe–Ge interatomic distance might be interpreted as a symmetryconserving transition and seems to be related to a magnetic phase boundary line.
