EVIDENCE OF STRONG CORRELATIONS BETWEEN ANOMALOUS LATTICE-PARAMETERS AND TRANSPORT-PROPERTIES IN CE16RU9

The new phase View the MathML source) was examined via the temperature dependences of the lattice parameters (10–300 K), magnetic susceptibility (1.5–300 K) and electrical resistivity (0.3–300 K). Different Ce valences (+4 and +3) for different crystallographic sites are proposed from magnetic data and are supported by previous structural results. No magnetic order is observed down to 0.3 K. Highly anisotropic stresses observed in the electrical resistivity temperature dependence are attributed to the anomalous thermal behaviour of the lattice parameter c.
