Description
| - At 320 K, the crystal structure of CeRuSn is commensurate with the related CeCoAl-type of structure by the doubling of the c lattice parameter. However, with lowering the temperature it becomes incommensurate with x and z position parameters at all three elemental sites being modulated as one moves along the c axis. The resulting crystal structure can be conveniently described within the superspace formalism in (3+1) dimensions. The modulation vector, after initially strong temperature dependence, approaches a value close to qnuc=(0,0,0.35). Below TN=2.8(1) K, CeRuSn orders antiferromagnetically with a propagation vector =(0,0,0.175), i.e. with the magnetic unit cell doubled along the caxis direction with respect to the incommensurate crystal structure. Ce moments appear to be nearly collinear, confined to the a–c plane, forming ferromagnetically coupled pairs. Their magnitudes are modulated between 0.11 and 0.95 B as one moves along the c axis.
