Abstract
We have studied the crystallographic and magnetic properties of CeNi11 -xSix compounds for x = 2 and x = 2.5. Both compounds have a structure that is derived from the tetragonal BaCd11 structure. For the compoun d CeNi9Si2 we have studied the preferred site occupancies of Si and Ni in more detail by time-of-flight neutron diffraction at room temperat ure. A strong site preference of the Si atoms for the crystallographic 8d position was observed. From magnetic measurements it is derived th at the Ce atoms in both compounds are close to tetravalent.
