Abstract

X-ray diffraction experiments were performed on polycrystalline and single-crystal specimens of Ce2 Fe17 at temperatures between 10 and 300 K. Below Tt =118±2 K, additional weak superstructure reflections were observed in the antiferromagnetically ordered state. The superstructure can be described by a doubling of the chemical unit cell along the c direction in hexagonal notation with the same space group R 3̄ m as the room-temperature structure. The additional antiferromagnetic satellite reflections observed in earlier neutron diffraction experiments can be conclusively related to the appearance of this superstructure.
