Abstract

The anisotropic thermal expansion parameters a(T), b(T) and c(T) of some RECu2, intermetallics (RE=Y, Er, Nd) has been measured in the temperature range from 400 K down to 4.2 K using X-ray powder diffraction. The influence of the crystal field on the thermal expansion in ErCu2 and NdCu2 has been determined by comparing the thermal expansion of the nonmagnetic isostructural YCu2 with the Er and Nd compounds. The data thus obtained are described theoretically using a set of crystal-field parameters deduced from the analysis of inelastic neutron diffraction data.
