Abstracts

EN

The lattice parameters a and c of CeM_{2}Sn_{2} show an anomalous temperature dependence compared to the analogous variations for LaM_{2}Sn_{2}. The anomaly Δa of thermal expansion for CeCu_{2}Sn_{2} has a maximum around 90 K, whereas Δc has a maximum near 140 K, near to the maximum of the magnetic resistivity Δρ.
