Sažetak
We examine the resistivity and thermopower of single crystal specimens of the pyrochlore oxide Cd2Re2O7 at pressures up to 2 GPa. Thermopower proves to be a sensitive tool in the study of the phase diagram of Cd2Re2O 7. The 200 K metal-to-metal phase transition is accompanied by a strong increase of the absolute value of the thermopower. A weaker anomaly allows us to identify a second phase transition at 125 K. Following the temperature dependence of this anomaly, we obtain the corresponding phase boundary up to 1.2 GPa, and argue that it must drop to T=0 before p reaches 1.8 GPa. There is a wide temperature range where the electrical properties are fairly sensitive to pressure, indicating the strong coupling of the electronic degrees of freedom to the lattice.
