Abstract

Neutron powder diffraction patterns are measured at 50Β°C and liquid nitrogen temperature. The crystal structure is defined as D8~8~ (space group P6~3~/mcm), in agreement with CASTELLIZ's data [2]. It is found that the atoms in the 4 (d) and 6 (g) positions have magnetic moments of (3 Β± 0.1) and (2 Β± 0.1) Bohr magnetons, respectively. The spin direction is parallel to the [0001] axis.

## Abstract Germanium‐based compounds have recently attracted considerable attention in Semiconductor Spintronics. The Mn~5~Ge~3~ compound have been grown on Ge(111) substrate so that epitaxial β€œspin valves” can be fabricated. Recent experiments suggest a spin structure that is likely non‐collinear
