| We present high temperature thermodynamical properties of a newly prepared Er2Ti2O7 single crystal investigated by means of dilatometry and differential scanning calorimetry measurements. Measured data are dominated by a wide anomaly between 1250 K and 1540 K. The high-temperature powder X-ray diffraction experiment subsequently demonstrates the anomaly to be related to changes within the pyrochlore lattice, however, preserving the crystal symmetry in the whole temperature range. |
