Abstract

We report the X-ray study for the pyrochlore oxide Cd2Re2O7. Two symmetry-lowering structural transitions were observed at Ts1=200 K and Ts2=120 K. The former is of the second order from the ideal cubic pyrochlore structure with space group Fd3m to a tetragonally distorted structure with I4m2, while the latter is of the first order likely changing to another tetragonal space group I4122. We discuss the feature of the lattice deformation.
